    A nutritional survey based on twelve adolescent male Kalenjin runners in Kenya during a 2-week field study was carried out in order to determine the composition of their diet and make a comparison with macronutrient recommendations for athletes. Food samples were collected for analysis of macronutrient distribution and energy content from main meals and the macronutrient distribution and energy content of additional food intake were based on the information of a 24 h recall interview and estimated from food tables. The diet of the Kalenjin runners was very high in carbohydrate (71 % 8.7 g/kg body weight per d) and very low in fat (15 %). Intake of total protein (13 %; 1.6 g/kg body weight per d) was above the daily intake recommended by the Food and Agriculture Organization/World Health Organization/United Nations University (FAO/WHO/UNU), while essential amino acid intake was estimated to be in the borderline-to-low range based on FAO/WHO/UNU recommendations for children Kalenjin runners met recommendations for endurance athletes for total protein and most essential amino acid intake as well as carbohydrate intake even though it was based on a small range of food items.

  4. Targeting the adolescent male.

    1986-01-01

    The National Urban League regards too early parenting among adolescents as an issue requiring high level, active attention from all segments of the Black community. Poverty, single parent households and adolescent pregnancies are not exclusively female problems. The role that males play has been missing from too many studies of these phenomena. In light of the fact that most sexual activity is male initiated, and most sexual behavior is male influenced, it becomes clear that there will be no resolution of the problem of teenage pregnancy without directing greater attention to the male. The issue of male responsibility is skirted too often due to parental pride on the part of mothers and fathers when their male children seek sexual relations with female partners. It is viewed as a sign that they are developing sexually within the norm. This is especially true, in many instances, in female headed households where the mother is concerned that she may not be providing her son with an adequate male role model. Sexual activity by female adolescents, however, is generally not condoned. This confusing double standard is further compounded by the disjointed fashion in which American society responds to adolescent sexuality on the whole. Although the home should be the focal point, many parents reluctantly admit an inability to communicate effectively about sex with their pre-adolescent children. Thus, the school, church, community and social agencies have all been enlisted in this task. The National Urban League's initiative in this area is expected to have significant impact on the course of adolescent sexuality and reproductive responsibility.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:3745498

    A sample of 100 adolescent males enrolled in 2 high schools in suburban New Jersey completed a 30 item questionnaire in 1980 to explore further the attitudes and intended behavior of white, middle-class adolescent males regarding their reproductive responsibility. Data were sought on attitudes toward sex, contraception, pregnancy, and fatherhood. Also questioned were preferences about contraceptive use as well as anticipated behavior in the event of a partner's pregnancy. The study also was designed to obtain information on responses the subjects anticipated from their paretns on preferred pregnancy outcome. All respondents were white. 94%, based on data on the subjects' fathers, were ranked middle class and higher according to Hollingshead's Two Factor Index of Social Position. Ages ranged from 15-19 with a mean age of 16. 88% were living in households with both parents. Only 4% agreed that there was nothing wrong with telling a girl that you love her (even if you do not) so that she will agree to have sexual relations. This contrasts markedly with 61% of Vadies and Hale's lower-class sample of adolescent males who felt that deception was acceptable to obtain sex. 59% of the study group agreed that contraceptive use "shows concern for the girl," but the percentage dropped slightly to 53% regarding attitude toward using "protection whenever possible." The subjects demonstrated a contrast between attitude and intended behavior with 67% indicating an intention to use contraception when participating in sex regularly. 62% thought that for most of their peers would have sex and count on luck. 54% assumed that the "girl will protect herself." Respondents were more often willing either to help the close girlfriend range an abortion (28%), to marry her (21%), or to help her seek an adoption (20%). They were less likely to do the same for a casual girlfriend except in the case of abortion. A double standard was significantly evident on the basis of several preferred types

  11. Male homosexuality: the adolescent's perspective.

    1987-03-01

    Although homosexual activity is prevalent among US teenagers, adolescent homosexuality per se has been a poorly understood phenomenon. The purpose of this investigation is to describe the meaning and experience of homosexuality from the adolescent's perspective. Twenty-nine male teenagers, self-described as gay (79%) or bisexual (21%), volunteered to participate in a structured interview, the purpose of which was to examine the definition of homosexuality, the acquisition of a gay identity, and the impact of sexuality on family, peers, and community. The youths demonstrated well-established sexual identities by the consistency of their sexual fantasies, interests, and behaviors over time. Homosexuality was more frequently described as a general attraction to men (48%) and an indicator of positive personal attributes (33%) than as an isolated sexual behavior. The subjects reported strong negative attitudes from parents (43%) and friends (41%) toward their sexualities. Discrimination (37%), verbal abuse from peers (55%), and physical assaults (30%) were frequently cited problems. These stressors may place the boys at high risk for physical and psychosocial dysfunction. PMID:3822631

  12. Anorexia nervosa and bulimia in adolescent males.

    Science.gov (United States)

    Andersen, A E

    1984-12-01

    Anorexia nervosa or bulimia in adolescent males occurs ten times less frequently than in adolescent females. When they occur, however, they can be clearly identified and differentiated from disorders also associated with weight loss such as swallowing phobias. Early diagnosis and treatment leads to improved outcome. While the formal psychopathology of male anorectics is similar to that of females, there is often a different motivation for the initial weight loss in males. They are more often concerned with attaining an idealized male body and avoiding teasing or criticism about their appearance. When males become ill, they tend to develop the full anorectic syndrome or not to become ill at all. Recognition of the special needs of adolescent males for individualized treatment increases the change of optimal outcome. Anorexia nervosa and bulimia in the teenage male should be seen as an ineffective method of dealing with developmental crises by gaining a sense of effectiveness and control through weight reduction and food restriction. Treatment seeks to improve quickly the starvation-related aspects of the illness while attempting to find more appropriate methods of dealing with the life crises prompting the illness. The real goal of treatment is to make the anorectic or bulimic illness unnecessary by encouraging the patient to continue the work of individuation and separation so that challenges in development and problems in living are resolved in a direct rather than an indirect way through an eating disorder.

    Full Text Available Objective:Substance abuse in adolescents may also be a marker to other harmful life styles. This study aims to find out the prevalence, pattern and sociodemographic risk factors of substance abuse in male adolescents. Methods:This study examined 390 male school children aged 10-19 years in the rural and urban areas of district Aligarh, Uttar Pradesh, India. Data was analyzed by SPSS -10. Findings:Substance abuse was prevalent in 13.3% of adolescents of whom 96.1% were using various forms of tobacco and 3.8% were taking alcohol. While there was statistically significant association between the substance abuse and the age group of adolescents and size of their families, variables such as religion, socioeconomic status, place of residence were not associated with substance use. Most of the students reported initiation of substance use at 14 yrs of age due to peer pressure. Conclusion:Peer educators would be a useful strategy for communication with adolescents to counter peer pressure. The prevention and control measures should be started at primary education level.

    Full Text Available Background Evidence indicates a relationship between perfectionism and eating disorder symptoms (EDS. However, there is no such empirical evidence in Brazilian scientific literature. Moreover, studies of EDS in the male sex are scarce. Objective To analyze a possible association between EDS and perfectionism traits in adolescent males. Methods Participants were 368 adolescents aged 12 to 15 years. We used the subscales of the Eating Attitudes Test (EAT-26 and the Multidimensional Perfectionism Scale to assess EDS and perfectionism traits, respectively. Results The results indicated a statistically significant association between the high perfectionism trait and EDS (X2 = 16.40; Wald = 15.92; p = 0.001. Moreover, the findings showed no difference in the scores of the Diet (F(1, 367 = 2.14; p = 0.23 or Concern for Food and Bulimia (F(1, 367 = 2.44; p = 0.19 subscales according to groups of perfectionism.

  11. Adolescent male peer sexual abuse: An issue often neglected

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available Traditionally, sexual abuse is under-reported and under-recognized when the victims are boys. A study carried out by the Government of India in 2007 suggests that every second child/adolescent in the country faces some form of sexual abuse and it is nearly equally prevalent in both sexes. The significance of the problem is undermined all the more when the abuse is perpetrated by a peer. Sexual activity between children and adolescents that occurs without consent or as a result of coercion is tantamount to abuse. A majority of the victims do not disclose the occurrence to anyone. This often neglected issue of adolescent male peer sexual abuse in a sexually conservative country like India is highlighted and discussed through this case, which came to light only after the victim developed a venereal disease.

    `The gradual reduction in the incidence of AIDS among men who have sex with men has not occurred in the youngest age group; on the contrary, it is growing. This paper examines the vulnerabilities of adolescent males at risk of HIV infection. This is a qualitative study conducted through interviews with HIV positive young men undergoing treatment, whose diagnosis was made during adolescence. The interviews were recorded and transcribed in full. They were analyzed by intensive reading, classified by issues, and interpreted from a hermeneutic-dialectic perspective in dialogue with the literature. We interviewed 16 young men whose diagnosis occurred between the ages of 11 and 19 and for all of them the method of HIV transmission was sexual; 12 of the men were homosexual and 4 were heterosexual. It was evident that vulnerable situations included disbelief in the possibility of contamination, subjection to sex, homophobia and commercial sexual exploitation. This study demonstrates the importance of the formulation of public policies on sexual and reproductive health, which include adolescents and young men. These policies should embody the perspective of masculinity in all its widest aspects, as well as actions in favor of sexual diversity. PMID:26132259

    This study examined male adolescents' self-report of rape of adolescent girls and the socio-demographic variables that correlated with self-report of rape. Descriptive-correlational design was used and the study was conducted in five public senior secondary schools in Ile-Ife, Nigeria. Three hundred and thirty-eight male adolescents participated in the study. A structured questionnaire was used to collect data. Findings from the study revealed the mean age of the adolescent males to be 16 years, with the majority (73%) of them in the middle adolescent stage. Six percent of the adolescent males reported they had raped an adolescent girl in the past. Among the boys who reported rape, 55% reported they had raped their sexual partners, and 55% reported they had perpetrated gang rape. Smoking (p = .0001), alcohol consumption (p = .001), and birth order (p = .006) predicted self-report of rape. The coefficient of birth order showed that odds of self-report of rape by first-born male increases by 6 times compared with other children. Study findings also provided evidence that adolescent males are moving from lone rape to gang rape in intimate partner relationships. Male adolescents are important group to target in rape prevention programs. PMID:25381280

    This study addresses the epidemiology of injuries in adolescent male and female soccer players in Germany. Therefore, the purpose of the study was to analyse the injuries in male and female youth soccer players in Germany. This study was designed as a cross-sectional web-based survey. From March until December 2011 we investigated 1110 soccer players (male n = 841; female n = 269) aged 12 - 19 years (15.0 ± 2.0 years) from 60 clubs in Southern Germany. A total of 664 (79 %) of the 841 boys and 67 (25 %) of the 269 girls reported being injured due to soccer. The total number of injuries was 2373. Respectively the frequency of injury was 2.85 in boys and 7.10 in girls. The lower extremities were affected in 70 % of all reported cases. Strains were the most common injuries in the lower and upper extremities (35 %). The boys reported in 51.5 % of all injuries that the injury was non-contact in nature. In contrast, 52.1 % of the injuries in girls were reported as contact injuries. Similar amounts of injuries were observed in training versus games for both genders. Prevention procedures, such as a thorough warm-up, should be implemented before every game and training to reduce the risk of injury. PMID:23446953

    Full Text Available Primary hyperparathyroidism (PHPT is a disorder of calcium homeostasis. We report the case of a 17-year-old adolescent male, who presented with an acute psychosis coinciding with severe hypercalcemia and markedly elevated intact parathyroid hormone (iPTH level and low vitamin D level. A Sestamibi scan showed a positive signal inferior to the left lobe of the thyroid gland. He had only a partial response to the initial medical and psychiatric management. The enlarged parathyroid gland was resected surgically and postoperatively serum calcium and iPTH levels normalized. The histopathology was compatible with a benign adenoma. Patient’s acute psychotic symptoms resolved gradually after surgery; however he remained under psychiatric care for the behavioral issues for about 6 months after surgery. While psychosis is a rare clinical manifestation of hypercalcemia secondary to PHPT in pediatric population, it should be considered as a clinical clue in an otherwise asymptomatic pediatric patient.

    This study investigated childhood psychopathology and Internet addiction in adolescents. Initial assessment data were obtained from 1998 to 1999, and a follow-up assessment was performed in 2006, when the original subjects entered middle school. Personal information for the 524 male subjects was obtained from the original data. The subjects were evaluated with the Korean version of the child behavior checklist, which was administered to the children's parents. Demographic and psychosocial factors were also evaluated. Children were reassessed with the self-reported Korea Internet Addiction Scale. Our results indicated that 3.6 % of the subjects had Internet addiction, and revealed a significant relationship between withdrawal and anxiety/depression and future Internet addiction. The results suggest that withdrawal and anxiety/depression during childhood should be considered in the etiology of problematic Internet use in boys. Accordingly, clinicians should consider anxiety/depression and withdrawal during childhood to prevent Internet addiction. PMID:23242708

  4. Risperidone-associated ejaculatory and urinary dysfunction in male adolescents.

    Holtmann, Martin; Gerstner, Sandra; Schmidt, Martin H

    2003-01-01

    We report two male adolescents who developed partial or complete retrograde ejaculation during risperidone treatment. Additionally, one patient complained of bladder outflow obstruction, and the other reported a reduced ejaculatory volume and decreased viscosity of semen. On rechallenge with risperidone, patient A showed a prompt recurrence of the ejaculatory dysfunction. The side effects were highly disturbing and led to reduced treatment compliance in both patients. The impact of risperidone, a strong alpha(1)-receptor antagonist, on the adrenergic system might induce retrograde ejaculation by altering the sympathetic tonus, allowing semen to pass retrogradely into the bladder during ejaculation. The reduced ejaculatory volume may be caused by risperidone-induced hyperprolactinemia. Clinicians should regularly inquire about sexual dysfunction and symptoms suggestive of hyperprolactinemia before starting risperidone treatment and regularly thereafter. PMID:12804132

    Full Text Available Abstract A cross-sectional study was conducted to identify the factors related to smoking habits of adolescents among secondary school boys in Kelantan state, Malaysia. A total of 451 upper secondary male students from day, boarding and vocational schools were investigated using a structured questionnaire. Cluster sampling was applied to achieve the required sample size. The significant findings included: 1 the highest prevalence of smoking was found among schoolboys from the vocational school; 2 mean duration of smoking was 2.5 years; 3 there were significant associations between smoking status and parents' smoking history, academic performance, perception of the health hazards of smoking, and type of school attended. Peer influence was the major reason students gave for taking up the habit. Religion was most often indicated by non-smokers as their reason for not smoking. Approximately 3/5 of the smokers had considered quitting and 45% of them had tried at least once to stop smoking. Mass media was indicated as the best information source for the students to acquire knowledge about negative aspects of the smoking habit. The authors believe an epidemic of tobacco use is imminent if drastic action is not taken, and recommend that anti-smoking campaigns with an emphasis on the religious aspect should start as early as in primary school. Intervention programs to encourage behavior modification of adolescents are also recommended.

    Full Text Available Background The prevalence of smoking in adolescents tends to increase. Smoking is associated with a higher risk of dyslipidemia. Objective To compare the lipid profiles of tobacco-smoking and non-tobacco-smoking male adolescents. Methods We performed a cross-sectional study in three vocational high schools in Yogyakarta from January to April 2011. Data on smoking status, duration of smoking and number cigarettes consumed per day were collected by questionnaires. We randomly selected 50 male smokers and 50 male non-smokers as the study subjects. Results Mean differences between smokers and non-smokers were 44.5 (95%CI 28.7 to 60.1 mg/dL for triglyceride levels; 8.0 (95% CI 1.0 to 14.9 mg/dL for low density lipoprotein (LDL cholesterol; 11.8 (1.1 to 22.4 mg/dL for total cholesterol and -5.7 mg/dL (95% CI -8.8 to -2.6 for high density lipoprotein (HDL cholesterol. Mean differences (95% CI between smokers who had engaged in smoking for >2 years and those who had smoked for ≤2 years were -18.1 (95% CI -33.9 to -2.3 mg/dL for total cholesterol; -49.4 (95% CI -67.2 to -31.5 mg/dL for triglycerides. Mean differences between those who smoked >5 cigarettes/day and ≤5 cigarettes per day were -18.4 (95% CI -32.8 to -4.1 mg/dL for total cholesterol and -29.1 (95% CI -53.6 to -4.6 mg/dL for triglycerides. Conclusion Smoking more than 5 cigarettes/day significantly increases total cholesterol, LDL cholesterol, and triglyceride levels, as well as reduces HDL cholesterol levels; while smoking more than 2 years significantly increases total cholesterol and triglyceride levels.

    Vaca, Federico E; Anderson, Craig L

    2011-01-01

    The adolescent Latino male mortality profile is an anomaly when compared to an otherwise more favorable overall U.S. Latino population mortality profile. Motor vehicle crash fatalities bear a considerable proportion of mortality burden in this vulnerable population. Friend influence and relational connection are two contextual domains that may mediate crash injury risk behavior in these adolescents. Our study goal was to assess the role of friend influence over time and relational connections associated with crash injury risk behavior (CIRB) in adolescent Latino males. Waves I and II data from the National Longitudinal Study of Adolescent Health were used. Scale of CIRB, and three relational connections; school connectedness, parent connectedness, and expectation of academic success were developed and tested. Friend nomination data were available and the index student responses were linked to friend responses. Linear regression was used to assess the relationship of relational connections and friend CIRB on index student CIRB at wave I and II. Longitudinal analysis did not show significant evidence for friend influence among adolescent Latino males on CIRB. The best predictor of CIRB at wave II for adolescent Latino males was their CIRB at wave I. Relational connections were important yet exaggerated cross-sectionally but their effect was substantially attenuated longitudinally. The lack of friend influence on CIRB for adolescent Latino males may be specific to this demographic group or characteristic of the sample studied. Prevention strategies that focus on modulating friend influence in adolescent Latino males may not yield the desired prevention effects on CIRB. PMID:22105382

    Full Text Available Objective: To study the prevalence of psychosocial problems in male adolescents and find out various factors contributing to psycho-social ill health. Methods: 500 adolescents were interviewed using a pre-tested structured questionnaire to elicit the information about the psychosocial problems including depression, suicidal thoughts and suicidal attempts. Association of academic performance, family problems, psychological problems and substance abuse was also included. Results: More than one third (39.6% adolescents were having psychological problems. These problems were significantly higher in middle adolescence (14-16 years, large extended families (> 8 members and lower socioeconomic status. Residence had no significant relation to psychological problems in the adolescents. On correlation, these adolescents with psychological problems were having significantly more academic problems, family disputes, domestic violence, lesser number of close friends and greater substance abuse. Conclusion: Considering that male adolescents from large families with lesser education and lower income had higher prevalence of psychosocial problems, it is essential for health care planners to design comprehensive family and health education programs for the adolescents. The family support, teacher student rapport and peer group communication should be strengthened to counteract unsafe behaviours in the adolescents.

    Murray, Kristen; Rieger, Elizabeth; Byrne, Don

    2015-02-01

    This study investigated the relationship between stress and body satisfaction in adolescence. A sample consisting of 515 adolescents aged 12-16 years completed a series of self-report questionnaires assessing general and specific aspects of adolescent stress, body satisfaction and the psychological constructs of self-esteem, depressive symptoms and body importance. Results revealed a significant association between higher body dissatisfaction and higher ratings of peer stress, lower self-esteem and greater body importance for female and male adolescents. These findings suggest that adolescent stress relates to satisfaction with the body and that this stress is specifically focused on the peer environment for both genders during adolescence. This may have implications for intervention programmes aimed at improving body satisfaction, suggesting that the inclusion of stress management training in these programmes could specifically focus on difficulties within the peer domain.

    Background Congenital cytomegalovirus (CMV) is a leading cause of disability, including sensorineural hearing loss, developmental delay, and mental retardation. Although the seroprevalence of CMV and associated exposure and behavioral risk factors have been reported in adolescent females, limited data exists in males. Method Serum was obtained from males (aged 12–17 years) from 6/2006 – 7/2007 in Cincinnati, OH, Galveston, TX, and Nashville, TN and tested for CMV IgG antibody using a commercial assay. Participants completed a computer assisted screening interview to assess seven risk categories. Results A total of 397 adolescent males were screened and 165 (47%) were seropositive. African American race, older age, and exposure to children ≤3 years of age in the home were significant predictors of CMV infection in the univariate analysis. Hispanic ethnicity, group living situations, saliva sharing behaviors, and intimate sexual contact were not associated with CMV infection. However, among those with a history of sexual contact, the number of life time partners was associated with CMV. In the final multivariate model, CMV seroprevalence was significantly higher in African American subjects (OR 1.99 (95% CI [1.27, 2.95]) and subjects >14 years of age (OR 1.1 (95%CI [1.00, 1.28]. With each additional risk factor, males had a 1.6x increased risk of CMV. Conclusions This study indicates that CMV infections are common in adolescent males, increase with age, and are associated with African American race. Further study is needed to understand these risk factors in preparation for a CMV vaccine targeted at both adolescent males and females. Summary This study indicates CMV infections are common in adolescent males, increase with age, and are associated with African Americans. Further study is needed to understand these risk factors in preparation for a CMV vaccine targeted at adolescent males and females. PMID:20936976

    1993-09-01

    Adolescence is an important period in the development of adult sexual offending against women, yet it has received little attention in research on attitudes toward women and rape. The present study used the Attitudes Toward Women Scale (AWS) and Burt's (1980) Rape Myth Acceptance Scale (BRMAS) to compare the attitudes of 31 male adolescents convicted of sexual assaults on women (rape, attempted rape, indecent assault) with the attitudes of 27 male adolescents convicted of nonsexual violent crimes. The results showed no significant difference between the two groups on either measure. Furthermore, a more traditional, conservative attitude toward women, as measured on the AWS, did not significantly correlate with the endorsement of rape myths as measured on the BRMAS. The findings are discussed with reference to the validity and reliability of these measures when used with adolescents. PMID:8271228

    Full Text Available Background and Objectives: The cognitive determinants of social behaviors play an important role in adolescents' decision-making for starting smoking. The present study was therefore conducted to determine the predictors of tobacco smoking in male adolescents in Hamadan, Iran, based on the Theory of Planned Behavior (TPB. Materials and Methods: The present descriptive-analytical study was conducted on 810 male high school students in Hamadan selected through the multistage sampling method. Data were collected using a self-report questionnaire with a section on participants' demographic information and another section based on the TPB constructs. Data were then analyzed in SPSS-18 and AMOS-18 using the Pearson correlation test and the indices of model fit. Results: Overall, 17.2% of the male adolescents reported to have smoked cigarettes in the past. Perceived behavioral control, subjective norms and attitude were the best predictors of behavioral intention for tobacco smoking, in the order of importance (P<0.001. Perceived behavioral control (&beta=-0.59 P<0.001 was a better predictor of the studied behavior than behavioral intention (&beta=0.11 P<0.001. In the structural equation model, TPB constructs accounted for 32% of behavioral intention variances and 50% of behavior variances. Conclusion: The results demonstrated the poor role of behavioral intention in reporting smoking behaviors in male adolescents. Other psychological factors that affect adolescents' decision-making regarding tobacco smoking should also be scrutinized.

    Background The orbitofrontal cortex (OFC) has consistently been implicated in the pathology of both drug and behavioral addictions. However, no study to date has examined OFC thickness in internet addiction. In the current study, we investigated the existence of differences in cortical thickness of the OFC in adolescents with internet addiction. On the basis of recently proposed theoretical models of addiction, we predicted a reduction of thickness in the OFC of internet addicted individuals....

    Adolescent males are practicing safer sexual behaviors and experiencing healthier outcomes than their predecessors. In recent years, adolescent males have tended to start having sex later in life, have fewer sexual partners, use condoms and other contraceptive methods more often, and father fewer children. Yet sexual activity during adolescence remains the norm, and thus adolescent sexual and reproductive health (SRH) remains an important concern. Moreover, large disparities remain in risk and outcomes according to race/ethnicity, sexual orientation, social connectivity, and where men live. Policy and program advances have been limited. Adolescent males are less likely than they were a decade ago to be receiving broad-based SRH information in school, and their access to clinical services has increased only marginally. Most new funding has been provided for ineffective abstinence-only education programs. Prerequisites for continued progress include research to fill in gaps in our knowledge, arriving at societal consensus around key controversies, and new tactics and allies in the political arena.

    Current models of adolescent drinking behavior hypothesize that alcohol expectancies mediate the effects of other proximal and distal risk factors. This longitudinal study tested the hypothesis that the effects of parental alcohol involvement on their children’s drinking behavior in mid-adolescence are mediated by the children’s alcohol expectancies in early adolescence. A sample of 148 initially 9–11 year old boys and their parents from a high-risk population and a contrast group of communit...

    2000-01-01

    Full Text Available To document knowledge and attitudes regarding sexuality and sexual practices of male adolescent high school students in Lima, Peru, a self-administered, anonymous survey was completed by 991 male adolescents aged 12-19 as part of a School-Based Sex Education Intervention model. Questions concerned sociodemographic information; family characteristics; personal activities; knowledge and attitudes regarding sexuality; sexual experience; and contraceptive use. Knowledge related to sexuality was limited. Males tended to mainly discuss sexuality with their male peers (49.8%. Attitudes towards sexual activity and condom use were largely positive, although some males expressed ambivalent feelings towards the latter. Of the sample, 43% had ever had sex; age at first sexual intercourse was 13 years. While 88% of the sample would use condoms, 74% also gave reasons for not using them. Sexual activity was related to age, ever having repeated a grade, living with only one parent or in a mixed family, activities such as going to parties, use of alcohol, tobacco, and drugs, and viewing pornographic videos or magazines. Many male adolescents were at risk of causing an unintended pregnancy or acquiring an STD.

  4. Educational Development and Detachment Processes of Male Adolescents from Immigrant Families

    Directory of Open Access Journals (Sweden)

    2010-11-01

    Full Text Available Social class, gender, and migration status notably influence social inequalities in the German educational system. Empirical studies reveal that especially male students from Turkish immigrant families belong to the most disadvantaged group with regard to educational opportunities. In order to identify causes for this we reconstruct and contrast biographies of successful and less successful educational careers of male adolescents from Turkish immigrant families. Our theoretical framework is based on the assumption that educational careers depend decisively on the way youths master the twofold challenge connected with adolescence and migration. Adolescent detachment processes are conceived as intergenerational occurrences (cf. King 2002, in which the quality of intergenerational family relationships as well as the biographical treatment of a particular migration project on the part of the parents play a significant role.

    García-Ael, Cristina; Cuadrado, Isabel; Molero, Fernando

    2013-01-01

    From the perspective of the Think manager--think male, this study was conducted to examine the type of leadership role depending on gender in a sample of 158 Spanish adolescents -according to three types of leaders: "male middle leader", "female middle leader" and "middle leader in general". The kind of emotional expression (positive and negative) evoked by their leadership behaviors (task- and relationship- oriented) was also analyzed. Lastly, whether adolescents' sexist beliefs affected the attribution of traits and the emotional expression towards these leaders was examined. Results showed that task-oriented traits were more characteristic of the leadership role than relationship-oriented traits. Adolescents expressed more positive emotions towards a task-oriented leader and towards a leader behaving in ways associated with both task- and relationship- oriented styles, but only for men. Finally, hostile sexism predicted fewer task-oriented traits to female leaders, more negative affect towards task-oriented male leaders and towards counter-stereotypic leaders. These results were moderated by the sex of adolescents. PMID:24230951

    Full Text Available The purpose of the study was to compare the linear kinematics of the barbell and the angular kinematics of the lower limb during the snatch lifts of two different barbell weights in elite male adolescent weightlifters. In the national team level, nine elite male adolescent weightlifters participated in the study. The snatch lifts were recorded by two video cameras under competitive conditions in preparation period before the European Junior Championship (Sony MiniDv PAL- 50 field/s and the two heaviest successful lifts were selected for kinematic analysis. The little toe, ankle, knee, hip, and shoulder on the body and one point on the barbell were digitized using Ariel Performance Analysis System (APAS, San Diego, CA, USA. Significant decreases were found in the maximum barbell height, the relative power output during the second pull, and the maximum vertical velocity of the barbell during the second pull of the heaviest lift (p < 0.05. Maximum extension velocity of the hip joint significantly increased during the first pull of the heaviest lift (p < 0.05. As the mass of the barbell increased, the maximum vertical velocity and the maximum height of the barbell and relative power output during the second pull decreased in the heaviest lift performed by adolescent weightlifters. Coaches should pay attention to assistant exercises to increase explosive strength during the second pull with maximum strength in male adolescent weightlifters.

    2014-01-01

    Full Text Available Primary hyperparathyroidism is a very rare complication following radioactive iodine therapy. There is typically a latency period of more than a decade following radiation exposure and, therefore, it is observed almost exclusively in adults. Consequently, pediatricians are not aware of the association. We present a case of primary hyperparathyroidism due to a solitary parathyroid adenoma occurring in an adolescent male two years following radioactive iodine treatment for papillary thyroid carcinoma. Periodic screening of serum calcium following ablative doses of radioactive iodine for thyroid cancer may be justified even in adolescents.

  18. Review: magnetic resonance imaging of male/female differences in human adolescent brain anatomy

    Directory of Open Access Journals (Sweden)

    Giedd Jay N

    2012-08-01

    Full Text Available Abstract Improvements in neuroimaging technologies, and greater access to their use, have generated a plethora of data regarding male/female differences in the developing brain. Examination of these differences may shed light on the pathophysiology of the many illnesses that differ between the sexes and ultimately lead to more effective interventions. In this review, we attempt to synthesize the anatomic magnetic resonance imaging (MRI literature of male/female brain differences with emphasis on studies encompassing adolescence – a time of divergence in physical and behavioral characteristics. Across all ages total brain size is consistently reported to be about 10% larger in males. Structures commonly reported to be different between sexes include the caudate nucleus, amygdala, hippocampus, and cerebellum – all noted to have a relatively high density of sex steroid receptors. The direction and magnitude of reported brain differences depends on the methodology of data acquisition and analysis, whether and how the subcomponents are adjusted for the total brain volume difference, and the age of the participants in the studies. Longitudinal studies indicate regional cortical gray matter volumes follow inverted U shaped developmental trajectories with peak size occurring one to three years earlier in females. Cortical gray matter differences are modulated by androgen receptor genotyope and by circulating levels of hormones. White matter volumes increase throughout childhood and adolescence in both sexes but more rapidly in adolescent males resulting in an expanding magnitude of sex differences from childhood to adulthood.

  19. Testosterone induces molecular changes in dopamine signaling pathway molecules in the adolescent male rat nigrostriatal pathway.

    Directory of Open Access Journals (Sweden)

    Tertia D Purves-Tyson

    Full Text Available Adolescent males have an increased risk of developing schizophrenia, implicating testosterone in the precipitation of dopamine-related psychopathology. Evidence from adult rodent brain indicates that testosterone can modulate nigrostriatal dopamine. However, studies are required to understand the role testosterone plays in maturation of dopamine pathways during adolescence and to elucidate the molecular mechanism(s by which testosterone exerts its effects. We hypothesized that molecular indices of dopamine neurotransmission [synthesis (tyrosine hydroxylase, breakdown (catechol-O-methyl transferase; monoamine oxygenase, transport [vesicular monoamine transporter (VMAT, dopamine transporter (DAT] and receptors (DRD1-D5] would be changed by testosterone or its metabolites, dihydrotestosterone and 17β-estradiol, in the nigrostriatal pathway of adolescent male rats. We found that testosterone and dihydrotestosterone increased DAT and VMAT mRNAs in the substantia nigra and that testosterone increased DAT protein at the region of the cell bodies, but not in target regions in the striatum. Dopamine receptor D2 mRNA was increased and D3 mRNA was decreased in substantia nigra and/or striatum by androgens. These data suggest that increased testosterone at adolescence may change dopamine responsivity of the nigrostriatal pathway by modulating, at a molecular level, the capacity of neurons to transport and respond to dopamine. Further, dopamine turnover was increased in the dorsal striatum following gonadectomy and this was prevented by testosterone replacement. Gene expression changes in the dopaminergic cell body region may serve to modulate both dendritic dopamine feedback inhibition and reuptake in the dopaminergic somatodendritic field as well as dopamine release and re-uptake dynamics at the presynaptic terminals in the striatum. These testosterone-induced changes of molecular indices of dopamine neurotransmission in males are primarily androgen

    Full Text Available Abstract Background The aim of the study was to evaluate psychopathy-like personality traits in a nationwide consecutive sample of adolescent male homicide offenders and to compare the findings with those of a randomly sampled adult male homicide offender group. A further aim was to investigate associations between psychopathic traits and offender and offence characteristics in adolescent homicides. Methods Forensic psychiatric examination reports and crime reports of all 15 to19- year- old male Finnish offenders who had been subjected to a forensic psychiatric examination and convicted for a homicide during 1995–2004 were collected (n = 57. A random sample of 57 adult male homicide offenders was selected as a comparison group. Offence and offender characteristics were collected from the files and a file-based assessment of psychopathic traits was performed using the Hare Psychopathy Checklist-Revised (PCL-R by trained raters. Results No significant differences existed between the adolescents and adults in PCL-R total scores, factor 2 (social deviance scores, or in facets 3 (lifestyle and 4 (antisocial. Adults scored significantly higher on factor 1 (interpersonal/affective and facets 1 (interpersonal and 2 (affective. The adolescent group was divided into two subgroups according to PCL-R total scores. One in five homicidal male adolescents met criteria for psychopathic personality using a PCL-R total score of 26 or higher. These boys significantly more often had a crime history before the index homicide, more frequently used excessive violence during the index homicide, more rarely lived with both parents until 16 years of age, had more institutional or foster home placements in childhood, had more school difficulties, more often had received special education, and, more often had contact with mental health services prior to age 18 years than boys scoring low on the PCL-R. They also more often had parental criminal history as well as homicide

    Previous studies have shown that the intake of freeze-dried strawberry powder (FDSP) improves select markers of cardiovascular health in adults with cardiovascular risk factors; however, whether these improvements can be observed in at-risk adolescents is unknown. A randomised, double-blind, cross-over study enrolled twenty-five overweight or obese males, aged 14-18 years, to consume 50 g of a FDSP or a control powder, daily for 1 week. Before and after each test period, measures of microvascular function, plasma nitrate/nitrite, platelet reactivity and blood lipids were collected at baseline and acutely 1 h after FDSP intake. Acute plasma nitrate/nitrite levels increased 1 h after consuming the FDSP during Study Visit 1 before daily FDSP intake (Pstrawberries can provide vascular health benefits to heavier adolescent males.

    Adolescents are the highest consumers of sugar sweetened drinks. Excessive consumption of such drinks is a likely contributor to the development of obesity and may be associated with enduring changes in the systems involved in reward and motivation. We examined the impact of daily sucrose consumption in young male and female rats (N=12 per group) across the adolescent period on the motivation to perform instrumental responses to gain food rewards as adults. Rats were or were not exposed to a sucrose solution for 2h each day for 28days across adolescence [postnatal days (P) 28-56]. They were then trained as adults (P70 onward) to lever press for a palatable 15% cherry flavored sucrose reward and tested on a progressive ratio (PR) schedule to assess motivation to respond for reinforcement. Female rats exposed to sucrose had higher breakpoints on the PR schedule than controls, whereas male rats exposed to sucrose had lower breakpoints than controls. These results show that consumption of sucrose during adolescence produced sex-specific behavioral changes in responding for sucrose as adults. PMID:26826605

Bioelectrical impedance analysis (BIA) was performed with a single-frequency tetrapolar impedance analyzer after the athletes had fasted overnight for 8 h. PA and BIVA were determined from BIA data. PA presented correlations (P athletes and also with age in adolescent (r = .63) and adult (r = -.27) athletes. Compared with adults, adolescent athletes presented lower PA and higher frequency of PA below the 5th percentile of a reference population (P athletes were different (P athletes were in the 95th percentile of BIVA tolerance ellipses and in quadrants consistent with adequate body cell mass and total body water. The adolescent athletes outside the 95th percentile ellipse were all football and basketball players who showed indications of decreased water retention and body cell mass and of increased water retention, respectively. PA and BIVA ellipses showed that the intense training routine of the athletes changed functional and hydration parameters and that the magnitude of these changes in adolescents may depend on the sport modality practiced.

    Full Text Available Background Systematic exercise leads to increased left ventricular mass, which may be misleading in a differential diagnosis of heart disease in athletes (physiologic hypertrophy versus pathologic hypertrophy. The cause of left ventricular hypertrophy is an important risk factor in the morbidity and mortality of cardiovascular diseases. Objective To compare left ventricular mass and left ventricular hypertrophy in male adolescent athletes and non-athletes. Methods We conducted a cross-sectional, analytic study, from September to December 2012 in male adolescents aged 15-18 years. The case group included athletes from the Bina Taruna Football Club Manado, while the control group included non-athlete adolescents. All subjects underwent history-taking, physical examinations and further supporting examinations. Left ventricular mass was measured by cardiovascular echocardio-graphy (Esaote Mylab 4.0 and calculated based on a formula. Left ventricular hypertrophy was defined as left ventricular mass of > 134 g/m2 body surface area. Results Subjects’ mean left ventricular masses were 359.69 (SD 188.4; 95%CI 283.58 to 435.81 grams in the athlete group and 173.04 (SD 50.69; 95%CI 152.56 to 103.51 grams in the non-athlete group, a statistically significant difference (P=0.0001. Ventricular hypertrophy was found 76.9% compared to 11.5% in the non-athlete group (P=0.0001. Conclusion Left ventricular mass in athletes is bigger than in non-athletes. In addition, left ventricular hypertrophy is more common in male adolescent athletes than in non-athletes. [Paediatr Indones. 2014;54:305-8.].

    Despite evidence that children of male war veterans with combat-related posttraumatic stress disorder (PTSD) are at particularly high risk for behavior problems, very little is currently known about suicidal behaviors in this population of youth. This study aimed to examine the prevalence and psychosocial correlates of suicide attempts among psychiatrically hospitalized adolescent offspring of Croatian male PTSD veterans. Participants were psychiatric inpatients, ages 12-18 years. Self-report questionnaires assessed demographics, suicide attempts, psychopathology, parenting style, and family functioning. The prevalence of suicide attempts was 61.5% (65.2% for girls and 58.0% for boys). Internalizing symptoms, family dysfunction, lower levels of maternal and paternal care, and paternal overcontrol were significantly associated with suicide attempts. Our findings suggest that suicide attempts are common among inpatient adolescent offspring of male PTSD veterans and that interventions targeting both adolescent psychopathology and family relationships are needed for adolescents who have attempted suicide.

    Tourette syndrome is a neurodevelopmental disorder characterized by multiple tics and commonly associated with behavioral problems, especially obsessive-compulsive disorder and attention-deficit hyperactivity disorder (ADHD). The presence of specific personality traits has been documented in adult clinical populations with Tourette syndrome but has been underresearched in younger patients. We assessed the personality profiles of 17 male adolescents with Tourette syndrome and 51 age- and gender-matched healthy controls using the Minnesota Multiphasic Personality Inventory-Adolescent version, along with a standardized psychometric battery. All participants scored within the normal range across all Minnesota Multiphasic Personality Inventory-Adolescent version scales. Patients with Tourette syndrome scored significantly higher than healthy controls on the Obsessiveness Content Scale only (P = .046). Our findings indicate that younger male patients with Tourette syndrome do not report abnormal personality traits and have similar personality profiles to healthy peers, with the exception of obsessionality traits, which are likely to be related to the presence of comorbid obsessive compulsive symptoms rather than tics.

    Chronic stress is an important cause for depression. However, not everyone who is exposed to chronic stress will develop depression. Our previous studies demonstrated that early adversity can cause lasting changes in adolescent rhesus monkeys, but depressive symptoms have not been observed. Compared to adults, it is still unknown that whether adolescent rhesus monkeys experiencing early adversity are more likely to develop depressive symptoms. In this study, we investigated the long term relationship between early adversity, chronic stress and adolescent depression for the first time. Eight male rhesus monkeys were reared in maternal separation (MS) or mother-reared (MR) conditions. All of them went through unpredictable chronic stress for two months at their age four. The stressors included space restriction, intimidation, long illumination and fasting. Behavioral and physiological data were collected during the experiment. The results showed that, compared with the MR group, the locomotor activity of MS group was significantly decreased after one month of chronic stress while huddling up and stereotypical behaviors were significantly increased. Moreover, this trend continued and even worsened at the second month. Significantly higher hair cortisol levels and lower body weight were observed in MS group after two months of stress. These results indicate that early adversity is one of the environmental factors which can increase the susceptibility of depression when experiencing chronic stress in the later life. This will further clarify the important roles of early environmental factors in the development of adolescent depression and children rearing conditions should receive more attention. PMID:27025444

    The seasonality of depressive symptoms is prevalent in children and adolescents. However, the mechanisms that underlie such susceptibility to seasonal influences on mood disorders are unclear. We examined the effects of a short photoperiod condition on the susceptibility to subchronic unpredictable mild stress (SCUS) and rhythmic alterations of plasma corticosterone (CORT), melatonin, and neuropeptide Y (NPY) in adolescent male rats. Compared with the 12h/12h light/dark photoperiod control (CON) rats, the 8h/16h photoperiod SCUS rats exhibited significant anhedonia, a core symptom of human depression, together with a blunted diurnal rhythm and elevation of 24h CORT, melatonin, and NPY levels. The 8h/16h photoperiod condition also blunted the rhythmicity of CORT, caused a phase inversion of melatonin, and caused a phase delay of NPY compared with 12h/12h CON rats. Such abnormalities of plasma CORT, NPY, and melatonin might cause adolescent individuals to present higher stress reactivity and greater vulnerability to stress over their lifetimes. The present study provides evidence of the susceptibility to the seasonality of stress-related disorders in adolescence. PMID:26655789

    Full Text Available Background: Aggressive behavior in adolescence can be expressed as a predictor for crime, substance abuse, depression and academic failure. The purpose of this study was to determine the prediction of aggression among Iranian adolescent based on theory of planned behavior (TPB as a theoretical framework. Methods: In this cross-sectional study, conducted in Yasuj County, south of Iran, during 2011, a total of 256 male adolescents, were randomly enrolled. Participants filled out a self-administered questionnaire. Data were analyzed by SPSS version 21 using bivariate correlations, and linear regression statistical tests at 95% significant level. Result: The three predictor variables of 1 attitude, 2 subjective norms, and 3 perceived behavioral control, accounted for 40% of the variation in the outcome measure of the aggression intention. Besides, intention accounted for 15% of the variation in the outcome measure of the aggression behavior. There was a significant correlation between drug abuse and alcohol consumption, have friend drug user, unprotect sex and parents divorced with aggression (P< 0.05. Conclusions: Designing intervention to reduction positive attitude and subjective norms toward aggressive behavior among adolescents could be use-fulness result to aggression prevention.

    Although the effect of labour and physical stress on the height and weight of growing children is relatively well known, rather limited information concerning the influences of the work environment on the physique of working children and adolescents is available. The purpose of this study was to increase our knowledge of the effects of mechanical stress on the human physique via somatotype during the adolescent growth period. Anthropometric measurements of 509 male apprentices aged 13.50-18.49 years and measurements of 451 nonworking youth (control group) of the same age group were taken. The members of both groups were from the lower socioeconomic strata and had similar living conditions. The apprentices were working an average of 11h per day in vocations requiring intense physical effort. The subjects were somatotyped using the Heath-Carter anthropometric protocol. The overall mean somatotypes were 2.3-4.4-3.3 for working adolescents, and 2.5-3.9-3.6 for the nonworking controls. A one-way multivariate analysis of variance (MANOVA) indicated significant differences between the groups. Working adolescents were more mesomorphic and less ectomorphic than their nonworking peers. In both groups, endomorphy decreased with age up to age 15; then remained stable for the labourers but increased for the nonworking peers. In both groups, mesomorphy was stable, but decreased with ectomorphy. These results indicate that physical stress not only causes retardation in linear growth, but also produces changes in human physique during the growth period. PMID:18222445

    The purpose of this study was to compare the resting-state plasma catecholamine and anxiety levels of Korean male adolescents with Internet game addiction (IGA) and those without IGA. This cross-sectional comparative study was conducted with 230 male high school students in a South Korean city. Convenience and snowball sampling methods were employed, and data were collected using (1) participant blood samples analyzed for dopamine (DA), epinephrine (Epi), and norepinephrine (NE) and (2) two questionnaires to assess IGA and anxiety levels. Using SPSS 15.0, data were analyzed by descriptive analysis, χ(2)-tests, t-tests, and Pearson's correlation tests. The plasma Epi (t = 1.962, p gaming over time induced decreased peripheral Epi and NE levels, thus altering autonomic regulation, and increasing anxiety levels in male high school students. Based on these physiological and psychological effects, interventions intended to prevent and treat IGA should include stabilizing Epi, NE, and anxiety levels in adolescents. PMID:26849530

    Spirituality and religion have been identified as important determinants of health for adults; however, the impact of faith-oriented factors on health behaviors and outcomes among African American adolescent males has not been well studied. The purpose of this study is to examine the relationship between religiosity and spirituality and obesity-related behaviors among 12-19 year old African American males (N = 105) in the Jackson Heart KIDS Pilot Study. Key variables of interest are church attendance, prayer, daily spirituality, weight status, attempts to lose weight, nutrition, physical activity, and stress. Daily spirituality is associated with whether an individual attempts to lose weight. The results from logistic regression models suggest that daily spirituality increases the odds that African American male adolescents attempt to lose weight (OR = 1.22, CI: 1.07-1.41) and have a history of diet-focused weight management (OR = 1.13, CI: 1.02-1.26). Future studies are needed to further explore the association between religion, spirituality, and obesity-related behaviors. PMID:27337622

    Decades of masculinity research have concluded that society places higher demands on males to adhere to norms for low emotional expression; yet, countless studies find that emotional expression is integral to well-being. Unfortunately, this contradiction places boys and men in a tenuous position as they must navigate a bombardment of societal messages about the importance of emotional stoicism and invincibility. For urban adolescents, the situation is more complicated as they encounter environmental stressors that place greater emphasis on projecting a tough façade. Thus, our primary aim was to assess to what degree dyads of close adolescent male friends from urban, low-income neighborhoods are able to engage in emotional expression and response and to explore some of the underlying mechanisms and interpersonal processes. Qualitative findings from our sample suggest that urban boys exhibit a wide range of behaviors when participating in dyadic emotional disclosure and response, including being highly emotionally expressive and supportive in the context of close male friendship.

    Full Text Available Objective: Goals for winning in sports can overshadow the virtues of fair play, friendship and unity among competitors. Adolescent athletes are using substances to achieve these goals, often at the expense of their health.The objectives of this study were to investigate the prevalence of performance enhancing substance (PES use in South African male adolescents and to determine which substances are regularly used. Moreover, the study investigated whether the subjects were using legal or illegal substances, and also determined the reasons for using these in sports. Design: The study used a cross-sectional study design, using a self-administered questionnaire adapted from a previous South African study that investigated doping in elite athletes. The questionnaire included questions on high school sport participation, nutritional supplements and doping substances used to enhance performance. The sample of subjects was obtained from male adolescent high school athletes involved in regular competitive sports at the 1st and 2nd sports team levels. Results: The results indicated that the prevalence of PES use in this sample was reasonably low (30/100. The subjects indicated a variety of substances used for performance enhancement, including banned substances, (namely, growth hormone (5/100, anabolic androgenic steroids (4/100, and adrenaline/ephedrine (4/100, and permissible supplements, (namely, creatine (32/100, vitamins (61/100, protein (61/100, caffeine (57/100 and carbohydrates (54/100. Conclusion: The findings indicate that the use of banned substances for performance enhancement is present. A holistic approach to educational interventions and behaviour change may help to reduce the prevalence of banned substance use in adolescents.

    Objective The aim of this study is to investigate psychological barriers (illness perceptions, insulin beliefs, and coping strategies) to optimal insulin therapy among adolescents with type 1 diabetes (T1D), with a specific focus on gender differences and mode of treatment (insulin pump vs pen). Methods A total of 105 males and females (12–20 years) participated in this study. The Brief Illness Perception Questionnaire, the Beliefs about Medicines Questionnaire, and the Adolescent Coping Orientation for Problem Experiences were completed. Additionally, diabetes clinical data were collected by the Norwegian Childhood Diabetes Registry. Results Females had significantly more negative illness perceptions than males on all dimensions (p<0.05), with moderate-to-large effect sizes. Regarding insulin beliefs, females scored significantly higher than males on insulin concern (p<0.001), indicating more concerns about insulin. There were no significant gender differences on perceptions of insulin necessity. Finally, females scored significantly higher on the coping strategies being social and solving family problems (p<0.01), indicating more positive coping among females than males for these subscales. In terms of treatment mode, the only statistically significant difference in the psychological aspects was for the illness perception treatment control, with patients using insulin pen reporting more negative perceptions on this dimension than patients using insulin pump. Conclusions Addressing psychological aspects may be a clinically important supplement to standard somatic T1D care. The consistent finding of gender differences across the psychological measures implies that a tailored treatment approach for males and females with T1D may be warranted. PMID:27403325

    IMPORTANCE Sexual violence can emerge in adolescence, yet little is known about youth perpetrators-especially those not involved with the criminal justice system. OBJECTIVE To report national estimates of adolescent sexual violence perpetration and details of the perpetrator experience. DESIGN, SETTING, AND PARTICIPANTS Data were collected online in 2010 (wave 4) and 2011 (wave 5) in the national Growing Up With Media study. Participants included 1058 youths aged 14 to 21 years who at baseline read English, lived in the household at least 50% of the time, and had used the Internet in the last 6 months. Recruitment was balanced on youths' biological sex and age. MAIN OUTCOMES AND MEASURES Forced sexual contact, coercive sex, attempted rape, and completed rape. RESULTS Nearly 1 in 10 youths (9%) reported some type of sexual violence perpetration in their lifetime; 4% (10 females and 39 males) reported attempted or completed rape. Sixteen years old was the mode age of first sexual perpetration (n = 18 [40%]). Perpetrators reported greater exposure to violent X-rated content. Almost all perpetrators (98%) who reported age at first perpetration to be 15 years or younger were male, with similar but attenuated results among those who began at ages 16 or 17 years (90%). It is not until ages 18 or 19 years that males (52%) and females (48%) are relatively equally represented as perpetrators. Perhaps related to age at first perpetration, females were more likely to perpetrate against older victims, and males were more likely to perpetrate against younger victims. Youths who started perpetrating earlier were more likely than older youths to get in trouble with caregivers; youths starting older were more likely to indicate that no one found out about the perpetration. CONCLUSIONS AND RELEVANCE Sexual violence perpetration appears to emerge earlier for males than females, perhaps suggesting different developmental trajectories. Links between perpetration and violent sexual

  10. Ready to die: a postmodern interpretation of the increase of African-American adolescent male suicide.

    African-Americans have typically registered lower rates of suicide than other ethnic groups. In the last 20 years this pattern has changed, particularly among young African-Americans between the ages of 15 and 19 (National Center for Injury Prevention and Control, Mortality Statistics, 1998, Atlanta, GA). Today, young African-American males are as likely to commit suicide as their White counterparts. To date, the research conducted regarding this phenomenon has been inconclusive and existing suicide interventions appear to have no effect on reducing this behavior among young African-Americans. This paper synthesizes classical (Durkheim, Suicide, 1979, Free Press, New York) and postmodern (Beck, Risk Society: Towards a New Modernity, 1992, Sage, London; Bauman, Modernity and Ambivalence, Cornell University Press, Ithaca, 1991) social theories in order to provide a more complete theoretical explanation for the increase in the suicide rate among adolescent African-American males. Postmodern society is typified by: (1) institutional deconstruction; (2) decreased collectivism; (3) increased normlessness and helplessness; and (4) exacerbated personal risk for stress. It is therefore possible to hypothesize that postmodernity characteristically loosens the bonds between the individual and society, thereby increasing vulnerability to depression, related pathologies (such as substance abuse), and suicide. African-Americans tend to be more affected/vulnerable because they are concentrated in resource-poor, low income areas, and institutions that provided social support (family, religious, community) and protected individuals from societal risk factors, have gradually been dissolving in postmodern societies. We argue that young African-American males of today are more exposed to stressors which increase psychological distress thus increasing depression and related pathological behaviors such as suicide. The main reason behind this increase is found in the inability of

    Full Text Available Abstract Background Limited data from positron emission tomography (PET studies of subjects with attention-deficit/hyperactivity disorder (ADHD indicate alterations in brain dopamine neurotransmission. However, these studies have used conventional univariate approaches that are less sensitive to detect complex interactions that may exist between different brain dopamine pathways and individual symptoms of ADHD. We aimed to investigate these potential interactions in adolescents with ADHD. Methods We used a 3D PET scan to measure utilization of native L-[11C]-DOPA to map dopamine presynaptic function in various cortical, striatal and midbrain regions in a group of 8 male adolescents with ADHD and 6 age matched controls. To evaluate the interactions between the studied brain regions, multivariate statistical methods were used. Results Abnormal dopaminergic function was found in multiple brain regions of patients with ADHD. A main finding was lower L-[11C]-DOPA utilization in adolescent with ADHD as compared to control subjects, especially in subcortical regions. This pattern of dopaminergic activity was correlated specifically with symptoms of inattention. Conclusion Dopamine signalling in the brain plays an important modulatory role in a variety of motor and cognitive functions. We have identified region-specific functional abnormalities in dopaminergic function, which may help better account for the symptoms of ADHD.

    Multiple theories suggest mechanisms by which the use of alcohol and drugs during adolescence could dampen growth in psychosocial maturity. However, scant empirical evidence exists to support this proposition. The current study tested whether alcohol and marijuana use predicted suppressed growth in psychosocial maturity among a sample of male serious juvenile offenders (n = 1,170) who were followed from ages 15 to 21 years. Alcohol and marijuana use prospectively predicted lower maturity 6 months later. Moreover, boys with the greatest increases in marijuana use showed the smallest increases in psychosocial maturity. Finally, heterogeneity in the form of age-related alcohol and marijuana trajectories was related to growth in maturity, such that only boys who decreased their alcohol and marijuana use significantly increased in psychosocial maturity. Taken together, these findings suggest that patterns of elevated alcohol and marijuana use in adolescence may suppress age-typical growth in psychosocial maturity from adolescence to young adulthood, but that effects are not necessarily permanent, because decreasing use is associated with increases in maturity.

    Full Text Available Objective: To examine inter-methods agreement between dual energy X-ray absorptiometry (DXA and air displacement plethysmography (ADP in male adolescent cyclists for assessing percentage of body fat (PBF. Methods: PBF of 24 male adolescent cyclists was assessed by DXA and ADP. Agreement between ADP and DXA was determined according to a Bland-Altman plot; validity and lack of agreement was assessed by calculating inter-methods difference. The limits of agreement and differences between methods were also calculated by paired t-tests. Heteroscedasticity was also examined. Results: The values obtained by DXA were higher than those obtained by ADP, and the graph presented heteroscedasticity (both p < 0.05; r = 0.74. Conclusion: DXA and ADP methods were not comparable in terms of PBF assessment in our sample of male adolescent cyclists; it needs to be taken into account when evaluating longitudinal changes in this determined population.

    The aims of this study were to examine the prevalence rates and multilevel correlates of cyberbullying victims and perpetrators among male adolescents diagnosed with attention-deficit/hyperactivity disorder (ADHD) in Taiwan. The relationships between cyberbullying involvement and depression, anxiety, and suicidality were also examined. The experiences of cyberbullying victimization and perpetration in 251 male adolescents with ADHD were assessed. Logistic regression analysis was used to examine the correlates of cyberbullying victims and perpetrators. The relationships between cyberbullying involvement and depression, anxiety, and suicidality were examined using multiple regression analysis. A total of 48 (19.1%) and 36 (14.3%) participants reported that they were cyberbullying victims or perpetrators, respectively. Those who had increased age and a higher parental occupational socioeconomic status, and reported more severe traditional passive bullying victimization were more likely to be cyberbullying victims. Those who had increased age and combined-type ADHD, and reported lower BAS reward responsiveness, more severe Internet addiction and more severe traditional passive bullying perpetration were more likely to be cyberbullying perpetrators. Cyberbullying victims reported more severe depression and suicidality than those who were not cyberbullying victims. A high proportion of male adolescents with ADHD are involved in cyberbullying. Clinicians, educational professionals, and parents of adolescents should monitor the possibility of cyberbullying involvement among male adolescents with ADHD who exhibit the cyberbullying correlates identified in this study.

    The objective of this study was to investigate knowledge, attitudes, and practices regarding AIDS among incarcerated male adolescents in Brazil and to develop an AIDS prevention intervention for this population. A questionnaire administered to 275 boys in São Paulo covered demographic and social characteristics, drugs, and HIV risk perception and behavior. Subsequently, we collected qualitative data on the development and implementation of a prevention program. Ninety-eight percent of adolescents were sexually experienced, most initiating by age 13; 22% were fathers. Injection drug use was reported by 5.5%, 12% had exchanged sex for money, 35% had more than 15 partners and 8% had homosexual experience. Although 72% had used condoms, only 9% used them consistently, and only 35% used one in their last intercourse before incarceration. Predictors of condom use included carrying condoms and endorsing the statement "I would use condoms with my girlfriend." Many said their lives include other risks more important than AIDS, such as survival in the crime scene. Initial efforts at prevention based on commonly used approaches of providing information to guide future rational decisions generated limited participation. However, when we worked with them to develop interventions based on their interests and needs, using modalities such as music, hip-hop arts, graffiti, and helping them to create an AIDS prevention compact disk, they responded with enthusiasm. These incarcerated adolescents are at extremely high social risk and report high levels of risk behavior for HIV infection. Interventions for these youth were better received when developed in collaboration with them and based on their beliefs, aspirations, and culture. The intervention that resulted went beyond AIDS to include issues such as violence, drugs, sexuality and human rights. PMID:12413191

    Administering manganese chloride (Mn) to rats on postnatal day (PD) 1-21 causes long-term reductions in dopamine transporter levels in the dorsal striatum, as well as a persistent increase in D1 and D2 receptor concentrations. Whether dopamine autoreceptors change in number or sensitivity is uncertain, although D2S receptors, which may be presynaptic in origin, are elevated in Mn-exposed rats. The purpose of this study was to determine if early Mn exposure causes long-term changes in dopamine autoreceptor sensitivity that persist into adolescence and adulthood. To this end, male rats were exposed to Mn on PD 1-21 and autoreceptor functioning was tested 7 or 70 days later by measuring (a) dopamine synthesis (i.e., DOPA accumulation) in the dorsal striatum after quinpirole or haloperidol treatment and (b) behavioral responsiveness after low-dose apomorphine treatment. Results showed that low doses (i.e., "autoreceptor" doses) of apomorphine (0.06 and 0.12 mg/kg) decreased the locomotor activity of adolescent and adult rats, while higher doses increased locomotion. The dopamine synthesis experiment also produced classic autoreceptor effects, because quinpirole decreased dorsal striatal DOPA accumulation; whereas, haloperidol increased DOPA levels in control rats, but not in rats given the nerve impulse inhibitor γ-butyrolactone. Importantly, early Mn exposure did not alter autoreceptor sensitivity when assessed in early adolescence or adulthood. The lack of Mn-induced effects was evident in both the dopamine synthesis and behavioral experiments. When considered together with past studies, it is clear that early Mn exposure alters the functioning of various dopaminergic presynaptic mechanisms, while dopamine autoreceptors remain unimpaired.

    1994-09-01

    Restructuring the personality, developing a new we-feeling, coping with drive thrusts and ego-syntonically reorganizing infantile conflicts are key developmental functions during adolescence. Some characteristics of male adolescence explain why especially male teen-agers are susceptible to joining right-wing extremist groups ready to use violence. The surroundings of right-wing extremist violence offers specific stabilizations which support the adolescent configuration of the enlarged self but as the same time they also lead to deformations of the personality. Establishing a greater self by ideology, self reparative transformation of self hatred to xenophobia, masking the personality and the regression of sexual desire to the desire of violence are consequences of processes of adaption and assimilation as described in cases of serious inner or outer threats.

    Using data from the Korea Youth Risk Behavior Web-based Survey, this study seeks to investigate associations of suicide attempts with family, individual, and behavioral factors on the basis of gender. Among male adolescents, those who did not live with their parents, who had poor subjective academic achievement, depression, experiences of smoking and sexual coitus, drug abuse, suicidal ideation and plans were more likely to attempt suicide. Among the female adolescents, those who did not live with their parents, had depression, low self-rated health, experiences of drug abuse and sexual coitus, and expressed unhappiness, suicidal ideation and suicide plans were more likely to attempt suicide. Thus, the development of a suicide prevention program for Korean adolescents requires different approaches for males and females. PMID:25812547

    Full Text Available Background: Obesity has become an epidemic across the globe and it is a multifaceted disease which requires multi-pronged combat strategy to control it. The new generations are at high risk of obesity in both developing and developed countries. Body mass index (BMI, is one of the important parameters, used to assess over weight of an individual. Aim of study: To find out the influence of food intake in the overweight of the male adolescents. Materials and Methods: A total of 1950 male adolescents (750 Indians and 1200 Nepalese; ratio = 5:8 participated in the study from India and Nepal during the period of 1st January to 31st July, 2014. The BMI was calculated using the height and weight of the subjects. Microsoft Excel and SPSS-v16 were used for the data analysis. Results: Out of 1950 male adolescents 660 [33.84%] were overweight. Among the overweight individuals, 540 (81.82% were non-vegetarians and 120 (18.18% were vegetarians. Conclusion: The increased prevalence of overweight among male adolescents is an indicative for developing and implementing effective dietary strategies for weight management. It is reported that intake of a low-fat, low-energy diet, over the course of one week in a stress-free environment, had positive impact on the risk factors of obesity related diseases. Promoting increased awareness of better physical culture and dietary habits are necessary to prevent obesity

    1992-03-01

    To determine correlates of condom use in adolescent males, we administered a sexual behavior questionnaire to 105 urban males attending a general adolescent clinic. The mean age was 16.5 +/- 1.6 years, and all reported heterosexual activity during the prior 3 months. Condom use was significantly (p less than 0.05) associated with perceived hassle of use (Spearman's rho = -0.40), perception of girlfriend's attitude toward condoms (rho = -0.36), self-confidence in correct use (rho = 0.26), younger age (rho = 0.25), reported degree of exposure to sexually transmitted disease (STD) education (rho = 0.23), perceived condom safety (rho = 0.23), and perceived risk of STD if not wearing a condom (rho = 0.21). Using stepwise multiple regression, four variables explained a significant amount of variation in condom use: perceived hassle of use, perceived girlfriend's attitude toward condom use, age, and self-confidence in correct use (adjusted R2 = 0.28, p less than 0.001). Intention to use free condoms was significantly (p less than 0.05) associated with past use (rho = 0.63), girlfriend's attitude toward use (rho = -0.46), self-confidence in correct use (rho = 0.36), perceived hassle (rho = -0.31), and degree of exposure to STD education (rho = 0.25). Three variables in a regression model explained a significant amount of variation in intent to use free condoms: self-reported past use, girlfriend's attitude, and self-confidence in correct use (adjusted R2 = 0.51, p less than 0.001).

    The present experiment was designed to determine whether individual variation in neurobiological mechanisms associated with substance abuse risk moderated effects of a brief preventive intervention on social competency skills. This study was conducted in collaboration with the ongoing preventive intervention study at Johns Hopkins University Prevention Intervention Research Center (JHU PIRC) within the Baltimore City Public Schools. A subsample (N = 120) of male 9th grade students was recruited from the larger JHU study population. Approximately half of the participants had a current or lifetime diagnosis of CD while the other half had no diagnosis of CD or other reported problem behaviors. Measures of executive cognitive function (ECF), emotional perception and intelligence were administered. In a later session, participants were randomly assigned to either an experimental or control group. The experimental group underwent a facilitated session using excerpted materials from a model preventive intervention, Positive Adolescent Choices Training (PACT), and controls received no intervention. Outcomes (i.e., social competency skills) were assessed using virtual reality vignettes involving behavioral choices as well as three social cognition questionnaires. Poor cognitive and emotional performance and a diagnosis of CD predicted less favorable change in social competency skills in response to the prevention curriculum. This study provides evidence for the moderating effects of neurocognitive and emotional regulatory functions on ability of urban male youth to respond to preventive intervention materials.

    2012-01-01

    Twenty-first century literacy is more than being able to encode for spelling ability, decode for reading comprehension, and calculate for numeric reasoning. It demands the skills to negotiate the world of technology. Health literacy is lower than general literacy, and general literacy is lower among African American males than the overall population. The authors discuss the prospects of incorporating Game Based Learning approaches into strategies for teaching health literacy. Results of a survey administered to youth to determine their level of involvement in video game playing indicate that key elements must be in place to ensure that a game will be played. These include action, strategy, and entertainment. Future investigation will examine the knowledge level of African American adolescent males of the nexus of certain concepts of climate change and health literacy. Climate change has significant implications for human health. This understanding will produce a scientifically based foundation for curricular and instructional decisions that include GBL. Results of this study will be used to design a video game concept and will contribute to the body of knowledge concerning environmental justice and empower individuals to make informed decisions about their own health and those they influence.

    1981-01-01

    Seventy convicted young male offenders were videotaped during a 5-min standardized interview with a previously unknown adult. In order to determine the social validity of the behavioral components of social interaction for this population, measures of 13 behaviors were obtained from the tapes. These measures were then correlated with ratings of friendliness, social anxiety, social skills performance, and employability made by four independent adult judges from the same tapes. It was found that measures of eye contact and verbal initiations were correlated significantly with all four criterion rating scales. The frequencies of smiling and speech dysfluencies were both significantly correlated with ratings of friendliness and employability. The amount spoken was found to be a significant predictor of social skills performance whereas the frequency of head movements influenced judgments of social anxiety. The latency of response was negatively correlated with social skills and employability ratings and the frequency of question-asking and interruptions correlated significantly with friendliness, social skills, and employability ratings. Finally, the levels of gestures, gross body movements, and attention feedback responses were not found to influence judgments on any of the criterion scales. The implications of the study for selection of targets for social skills training for adolescent male offenders are discussed. PMID:7287599

    There is a high prevalence of low back pain (LBP) in adolescent male rowers. In this study, regional lumbar spinal kinematics and self-reported LBP intensity were compared between 10 adolescent rowers with moderate levels of LBP relating to rowing with 10 reporting no history of LBP during a 15-minute ergometer trial using an electromagnetic tracking system. Adolescent male rowers with LBP reported increasing pain intensity during ergometer rowing. No significant differences were detected in mean upper or lower lumbar angles between rowers with and without LBP. However, compared with rowers without pain, rowers with pain: (1) had relatively less excursion of the upper lumbar spine into extension over the drive phase, (2) had relatively less excursion of the lower lumbar spine into extension over time, (3) had greater variability in upper and lower lumbar angles over the 15-minute ergometer trial, (4) positioned their upper lumbar spine closer to end range flexion for a greater proportion of the drive phase, and (5) showed increased time in sustained flexion loading in the upper lumbar spine. Differences in regional lumbar kinematics exist between adolescent male rowers with and without LBP, which may have injury implication and intervention strategies. PMID:26252195

    One emerging avenue for the exploration of adolescents' sexual orientation identity development is the Internet, since it allows for varying degrees of anonymity and exploration. The purpose of this phenomenological study was to examine the role of the Internet in facilitating the sexual orientation identity development process of gay and bisexual male adolescents. Qualitative interviews were conducted with an ethnically diverse sample of 63 gay/bisexual male adolescents (ages 15-23). Participants reported using a range of Internet applications as they explored and came to accept their sexual orientation identity, with the intended purpose and degree of anonymity desired determining which applications were used. Youth reported that the Internet provided a range of functions with regard to the exploration and acceptance of their sexual orientation identity, including (1) increasing self-awareness of sexual orientation identity, (2) learning about gay/bisexual community life, (3) communicating with other gay/bisexual people, (4) meeting other gay/bisexual people, (5) finding comfort and acceptance with sexual orientation, and (6) facilitating the coming out process. Future research and practice may explore the Internet as a platform for promoting the healthy development of gay and bisexual male adolescents by providing a developmentally and culturally appropriate venue for the exploration and subsequent commitment to an integrated sexual orientation identity.

    Full Text Available Abstract Background The physical environments in which adolescents reside and their access to food stores may influence their consumption of fruit and vegetables. This association could either be direct or mediated via psychosocial variables or home availability of fruit and vegetables. A greater understanding of these associations would aide the design of new interventions. The purpose of this study was to examine associations between distance to food stores and restaurants and fruit and vegetable consumption and the possible mediating role of psychosocial variables and home availability. Methods Fruit and vegetable consumption of 204 Boy Scouts was assessed by a food frequency questionnaire in 2003. Participant addresses were geo-coded and distance to different types of food stores and restaurants calculated. Fruit and vegetable preferences, home availability and self-efficacy were measured. Regression models were run with backward deletion of non-significant environmental and psychosocial variables. Mediation tests were performed. Results Residing further away from a small food store (SFS (convenience store and drug store was associated with increased fruit and juice and low fat vegetable consumption. Residing closer to a fast food restaurant was associated with increased high fat vegetable and fruit and juice consumption. Vegetable preferences partially mediated (26% the relationship between low fat vegetable consumption and distance to the nearest SFS. Conclusion Distance to SFS and fast food restaurants were associated with fruit and vegetable consumption among male adolescents. Vegetable preferences partially mediated the distance to low fat vegetable relationship. More research is needed to elucidate how environmental variables impact children's dietary intake.

  13. Consequences of adolescent ethanol exposure in male Sprague-Dawley rats on fear conditioning and extinction in adulthood

    Broadwater, Margaret A.

    Some evidence suggests that adolescents are more vulnerable than adults to alcohol-induced cognitive deficits and that these deficits may persist into adulthood. Five experiments were conducted to assess long-term consequences of ethanol exposure on tone and context Pavlovian fear conditioning in male Sprague-Dawley rats. Experiment 1 examined age-related differences in sensitivity to ethanol-induced disruptions of fear conditioning to a pre-conditioning ethanol challenge. Experiments 2 examined fear conditioning 22 days after early-mid adolescent (P28-48) or adult (P70-90) exposure to 4 g/kg i.g. ethanol or water given every other day (total of 11 exposures). In Experiment 3, mid-late adolescents (P35-55) were exposed in the same manner to assess whether timing of ethanol exposure within the adolescent period would differentially affect later fear conditioning. Experiment 4 assessed the influence of prior adolescent or adult ethanol exposure on the disrupting effects of a pre-conditioning ethanol challenge. In Experiment 5, neurogenesis (doublecortin---DCX) and cholinergic (choline acetyltransferase---ChAT) markers were measured to assess potential long-term ethanol-induced changes in neural mechanisms important for learning and memory. Results indicated that the long-lasting behavioral effects of ethanol exposure varied depending on exposure age, with early-mid adolescent exposed animals showing attenuated context fear retention (a relatively hippocampal-dependent task), whereas mid-late adolescent and adult exposed animals showed slower context extinction (thought to be reliant on the mPFC). Early-mid adolescent ethanol-exposed animals also had significantly less DCX and ChAT expression than their water-exposed counterparts, possibly contributing to deficits in context fear. Tone fear was not influenced by prior ethanol exposure at any age. In terms of age differences in ethanol sensitivity, adolescents were less sensitive than adults to ethanol

    Full Text Available Teenage pregnancy is one of the many public health problems facing the community in Bophuthatswana and neighbouring areas: Health professionals have attempted to address the problem yet little has been done to determine the role of the adolescent male in the prevention of this community problem. This study addresses the male adolescent’s sexual behaviour, his attitude towards contraception, contraceptive use and premarital pregnancy. The study revealed that most of the respondents commenced sexual practices at about 12years of age. These young men believed that girls should prove their fertility before marriage, although they viewed contraception as a joint responsibility between the two partners. The respondents were found to have a positive attitude towards contraception and contraceptive use, yet when they were asked what method of contraception they used since they were sexually active, only 24,5% reported use of a condom. Ignorance about reproduction and the effects of contraceptives Was confirmed When 48% of the respondents indicated that they were unaware of the fact that pregnancy could result from first coitus, and they also believed that oral contraceptives had dangerous side effects. The study further revealed that parents did not discuss teenage pregnancy and contraception with their children, instead this subject was discussed among friends at school. Respondents expressed fear when asked why the subject was never discussed with parents, some actually stated that their parents would ‘flog’ them if they initiated the subject on sex and related matters. The urgent need for formalised sex education in Bophuthatswana was expressed by 77% of the respondents.

    Research on prosocial attitudes, social networks, social capital, and social stratification suggest that lower-socioeconomic status (SES), Hispanic, and nonwhite individuals will be more likely than their higher-SES and non-Hispanic white counterparts to engage in health behaviors that serve a social good. Analyzing data from the University of North Carolina Human Papillomavirus (HPV) Immunization in Sons Study, we test whether SES and race-ethnicity are associated with willingness to vaccinate via prosocial attitudes toward HPV vaccination among adolescent males (n = 401) and parents (n = 518). Analyses revealed that (a) parents with lower education and (b) black and Hispanic parents and adolescent males reported higher prosocial vaccination attitudes, but only some attitudes were associated with higher willingness to vaccinate. We discuss these findings in terms of how prosocial attitudes may motivate certain health behaviors and serve as countervailing mechanisms in the (re)production of health disparities and promising targets of future public health interventions.

    2015-09-01

    The recognition of the seriousness of intimate partner violence (IPV) and the need to prevent it has led to the study of its inception in relationships established in adolescence. This study uses latent class analysis to establish a typology of male adolescents based on self-reports of violence against a girl in dating relationships. The participants were 4,147 boys in Spain aged 14 to 18 years from a probabilistic sample. Four discrete, identifiable groups were derived based on 12 indicators of emotional abuse, intimidation, coercion, threats, physical violence, and violence transmitted via communication technologies. The first group consists of non-violent adolescent boys. A second group comprises those boys who isolate and control their partners. Boys who exert only medium-level emotional abuse form the third group, whereas the fourth is formed by teenage boys who frequently engage in all types of violence. Compared with the non-violent adolescents in a multinomial logistic regression, the other groups show lower self-esteem and display a greater justification of male dominance and IPV against women; greater justification of aggression in conflict resolution; they have also received more dominance and violence messages from adults in their family environment; and they perceive IPV behaviors against women as abuse of lesser importance.

    2014-11-01

    Full Text Available Due to high training loads and frequently repeated unilateral exercises, several types of sports training can have an impact on the process of posture development in young athletes. The objective of the study was to assess and compare the postures of adolescent male volleyball players and their non-training peers. The study group comprised 104 volleyball players while the control group consisted of 114 non-training individuals aged 14-16 years. Body posture was assessed by the Moiré method. The volleyball players were significantly taller, and had greater body weight and fat-free mass. The analysis of posture relative to symmetry in the frontal and transverse planes did not show any significant differences between the volleyball players and non-athletes. Postural asymmetries were observed in both the volleyball players and the control participants. Lumbar lordosis was significantly less defined in the volleyball players compared to non-training individuals while no difference was observed in thoracic kyphosis. All athletes demonstrated a loss of lumbar lordosis and an increase in thoracic kyphosis. Significant differences in anteroposterior curvature of the spine between the volleyball players and the non-athletes might be associated with both training and body height. Considering the asymmetric spine overloads which frequently occur in sports training, meticulous posture assessment in young athletes seems well justified.

    2010-01-01

    In the discourse on health, boys are emerging as a problem group. In contrast to girls who tended to be seen as fragile if not sickly, boys used to be thought of as strong and healthy. Gender-specific concepts stipulated much more exercise for boys, the masturbation discourse prevented a relaxed relationship to the own body. The paper first describes specific problems in the biography (babies, child labour, tuberculosis, school, fitness for military service) and their solutions up to the time of the Weimar Republic. During and after the two world wars school boys tended to be of poorer health than girls. The consequences of war affect the mental health of (half-) orphans gender-non-specifically up to the third generation. After 1945, attention to health concerns is rather restricted to the professional aptitude of mining trainees, health-related risk behaviour tends to be interpreted in terms of gender. Mothers sought medical advice slightly more frequently on behalf of boys up to puberty. Concerning the time between 1780 and 2010 inferior health is often noticeable in boys and male adolescents. This used to, and still does, apply to babies, child labour, industrial work and occupational accidents, conscription and direct consequences of war. It was mostly due to gender-specific separation of labour, but partly also to a higher risk preference. The gender-specific wider scope for exercise and sports up to the 1960s, in contrast, had a health-promoting effect. PMID:21796900

    Maturation of social cognition and a gain in social proficiency are universal aspects of adolescent development that prepare individuals for adulthood. Social cognition involves the perception and interpretation of social cues, followed by the generation of a behavioral response. Social proficiency is acquired through the ability to make behavioral adaptations as one learns from social experience; increased social proficiency facilitates successful social interactions. In males, the neuroendo...

    It has been suggested that child sexual abuse is related to poor attachment to parents, which is associated with an inability to form intimate relationships. Seto and Lalumière indicated that there were too few studies of adolescent males to determine whether poor attachment was associated with perpetration. This study was designed to follow up on a previous study and further explored the association between insecure attachment to parents, social isolation, and interpersonal adequacy to child sexual abuse perpetration in adolescents. We compared two samples of adolescent males who had committed sexual offenses, those who committed offenses against children (n = 140) and those who committed offenses against peer or adults (n = 92), with a sample of similarly aged males in treatment for mental health or substance use issues (n = 93). Data were collected using a semi-structured interview and computer-administered questionnaire. We found an indirect association between anxious attachment and sexual offenses against child victims, which was accounted for by measures of social involvement and social isolation. These involvement and isolation measures also did not have a direct association with sexual offenses against child victims, in that their contribution was accounted for by a measure of Masculine Adequacy. This Masculine Adequacy, combined with decreased levels of Sexual Preoccupation and Hypersexuality and increased Sexual Compulsivity, was associated with commission of child sexual abuse. The interpersonal variables did not enter a model predicting sexual offending against peers/adults, which seemed solely associated with the interaction between Sexual Compulsivity and Hypersexuality.

    Adolescence is a unique period of development, marked by maturation of the prefrontal cortex (PFC), a region important for executive functioning. During this time, the human PFC decreases in overall volume and thickness. Likewise in adolescent rodents, losses of neurons, dendrites, dendritic spines and neurotransmitter receptors have been documented within the medial prefrontal cortex (mPFC), sometimes with sex and layer specificity. However, changes in the number of synapses during this time have not been examined. In the present study, we stereologically quantified the number of synaptophysin-immunoreactive boutons in the male and female rat mPFC across multiple time points from the juvenile period through adulthood (postnatal days (P) 25, 35, 45, 60 and 90). In females, there was a significant decrease in synaptophysin boutons between P35 and P45, coinciding with the onset of puberty. In males, there was no significant main effect of age on synaptophysin boutons; however, in both males and females, pubertal onset was associated with significant synaptic losses. These results suggest that puberty is a critical period for synaptic pruning within the rat mPFC, potentially contributing to maturation of adolescent executive function.

    Full Text Available Collecting accurate and reliable nutritional data from adolescent populations is challenging, with current methods providing significant under-reporting. Therefore, the aim of the study was to determine the accuracy of a combined dietary data collection method (self-reported weighed food diary, supplemented with a 24-h recall when compared to researcher observed energy intake in male adolescent soccer players. Twelve Academy players from an English Football League club participated in the study. Players attended a 12 h period in the laboratory (08:00 h–20:00 h, during which food and drink items were available and were consumed ad libitum. Food was also provided to consume at home between 20:00 h and 08:00 h the following morning under free-living conditions. To calculate the participant reported energy intake, food and drink items were weighed and recorded in a food diary by each participant, which was supplemented with information provided through a 24-h recall interview the following morning. Linear regression, limits of agreement (LOA and typical error (coefficient of variation; CV were used to quantify agreement between observer and participant reported 24-h energy intake. Difference between methods was assessed using a paired samples t-test. Participants systematically under-reported energy intake in comparison to that observed (p < 0.01 but the magnitude of this bias was small and consistent (mean bias = −88 kcal·day−1, 95% CI for bias = −146 to −29 kcal·day−1. For random error, the 95% LOA between methods ranged between −1.11 to 0.37 MJ·day−1 (−256 to 88 kcal·day−1. The standard error of the estimate was low, with a typical error between measurements of 3.1%. These data suggest that the combined dietary data collection method could be used interchangeably with the gold standard observed food intake technique in the population studied providing that appropriate adjustment is made for the systematic under

    Adolescent males' HPV vaccine initiation and completion in the United States is far below the Healthy People 2020 goal of 80% 3-dose completion among boys. In 2012, less than 7% of males ages 13-17 years had completed the 3-dose series. The Diffusion of Innovations framework guided this investigation of factors related to early adoption of HPV vaccination among male adolescents. Provider-validated data from the 2012 National Immunization Survey-Teen (NIS-Teen) for male adolescents ages 13-17 years were analyzed via a multivariable Poisson regression to estimate prevalence ratios for factors associated with HPV vaccine initiation and completion. Adolescent males who are Hispanic and those who are up to date on other recommended adolescent vaccinations were most likely to complete the HPV vaccine. Public health interventions are needed to improve low HPV vaccination rates among adolescent males in the United States. Description of early adopters of the HPV vaccine provides historical context of HPV vaccination acceptance that is needed to inform the design of targeted vaccination interventions to prevent negative HPV-associated outcomes.

    Chewing behavior may show sex differences; thus, the present study aimed to compare the masticatory aspects and the prediction of masticatory performance between male and female adolescents. Ninety-one healthy subjects (47 girls, 44 boys), caries-free and aged 14-17years, were included. Masticatory performance and maximal bite force were evaluated using a color-changeable chewing gum and digital gnathodynamometer, respectively. Masticatory behavior was assessed by the subjective aspect of the quality of the masticatory function (validated questionnaire) and the Orofacial Myofunctional Evaluation with Scores expanded (OMES-e) was used to determine chewing time, frequency of chewing cycles and other aspects. Salivary flow rate was also assessed. The physical examination involved measurements of facial morphometry, body weight, height, skeletal muscle mass, and dental/occlusal evaluations. It was observed that boys showed larger facial dimensions, higher bite force and chewing frequency and better masticatory performance than girls. They also showed shorter chewing time, fewer chewing cycles and lower score for OMES-e (that is, more changes in orofacial myofunctional aspects). Bite force showed a weak correlation with skeletal muscle mass only in boys (r=0.3035; p=0.0451). The masticatory performance was dependent on the bite force in boys (Adj R(2)=19.2%; Power=84.1%); among girls, masticatory performance was dependent on the frequency of chewing cycles and masticatory behavior (subjective aspect) (Adj R(2)=34.1%; Power=96.1%). The findings support the existence of sex differences in many masticatory aspects of function and behavior, hence the importance of considering sex differences when evaluating masticatory function and myofunctional therapy outcomes among young subjects.

    The prevalence of obesity in children and adolescents has increased rapidly over the past 30 years, as has the incidence of attention deficit hyperactivity disorder (ADHD). In 2012, it was found that overweight children have a twofold higher chance of developing ADHD than their normal weight counterparts. Previous work has documented learning and memory impairments linked to consumption of an energy-dense diet in rats, but the relationship between diet and ADHD-like behaviors has yet to be explored using animal models. Therefore, the purpose of this study was to explore the role of diet in the etiology of attention and hyperactivity disorders using a rat model of diet-induced obesity. Male Sprague-Dawley rats were fed either a control diet or a Western-style diet (WSD) for ten weeks, and specific physiological and behavioral effects were examined. Tail blood samples were collected to measure fasting blood glucose and insulin levels in order to assess insulin insensitivity. Rats also performed several behavioral tasks, including the open field task, novel object recognition test, and attentional set-shifting task. Rats exposed to a WSD had significantly higher fasting insulin levels than controls, but both groups had similar glucose levels. The quantitative insulin sensitivity check index (QUICKI) indicated the development of insulin resistance in WSD rats. Performance in the open field test indicated that WSD induced pronounced hyperactivity and impulsivity. Further, control diet animals were able to discriminate between old and novel objects, but the WSD animals were significantly impaired in object recognition. However, regardless of dietary condition, rats were able to perform the attentional set-shifting paradigm. While WSD impaired episodic memory and induced hyperactivity, attentional set-shifting capabilities are unaffected. With the increasing prevalence of both obesity and ADHD, understanding the potential links between the two conditions is of clinical

    Full Text Available Background Tobacco smoking among adolescents has been a concern for researchers and health organizations in recent years. However, predisposing factors to smoking initiation among Iranian adolescents are not well recognized. Objectives This study aimed to determine the prevalence of tobacco smoking and to investigate the role of psychologic, behavioral, and demographic risk factors in adolescents' smoking status. Patients and Methods This cross-sectional study was performed on 810 male adolescents recruited through cluster random sampling method in Hamadan in 2014. The participants received a self-administered questionnaire that contained questions about tobacco smoking behavior and demographic, behavioral, and psychologic variables. Data were analyzed by SPSS16 through independent-samples t test, Chi square, and logistic regression. Results A total of 139 persons (17.1% were tobacco smoker and the mean (SD age at smoking initiation was 13.7 (2.2 years. Sense of need, decreasing stress, having a smoker friend, and inability to reject smoking suggestion were common reasons associated with tobacco smoking (P < 0.05. In addition, statistically significant differences between tobacco smokers and nonsmokers were found in the age, grade, mother's job, and education (P < 0.05. In comparison to non-smokers, tobacco smokers evaluated a typical smoker as less immature, more popular, more attractive, more self-confident, more independent, and less selfish person (P < 0.05. Conclusions The results showed that the effect of several psychosocial, behavioral, and demographic risk factors on adolescents' smoking status. Thus, design and implementation of interventions based on the results of the present study may be effective in preventing tobacco smoking among adolescents.

    A study was conducted to examine how interpersonal norms, media norms, attitudes, perceived behavioral control, perceived barriers, and self-efficacy had an influence on healthy eating intention among adolescents. A probability sample of 544 adolescents aged 12 to 18 was conducted. Results indicated that girls had a more favorable attitude and intention toward healthy eating than boys. Healthy eating intention among boys was predicted by attitude, perceived behavioral control, perceived barriers, and self-efficacy, and among girls was predicted by perceived behavioral control and self-efficacy. Different marketing strategies to promote healthy eating among adolescent boys and girls should be adopted. PMID:25405634

    Full Text Available OBJETIVO: Analisar as relações de gênero vivenciadas por adolescentes do sexo masculino e como elas contribuem para torná-los vulneráveis à gravidez na adolescência. MÉTODOS: Estudo qualitativo realizado em Campo Grande, Mato Grosso do Sul, em 2003. Participaram 13 adolescentes masculinos com menos de 20 anos, com um único filho de até 11 meses, cuja mãe estava na mesma faixa etária do pai. Realizaram-se entrevistas semi-estruturadas gravadas. Após transcrição, procedeu-se à análise temática de conteúdo. RESULTADOS: Identificaram-se estereótipos de gênero em que se destacavam papéis de líder, provedor e ativo sexualmente, bem como a rejeição a ser cuidador. Esses papéis apareceram consolidados principalmente na perspectiva dos entrevistados acerca do trabalho como marcador de sua condição de homem e provedor da família. A liderança dos adolescentes prevaleceu no relacionamento com a mãe de seu filho, notadamente na iniciativa das relações sexuais e no uso de contraceptivos. A gravidez foi considerada por eles como "por acaso" e inesperada, mas a paternidade foi vivenciada como uma prova final de sua condição de homens adultos. CONCLUSÕES: Verificou-se a condição de vulnerabilidade dos adolescentes para a paternidade em virtude da socialização de gênero nos moldes tradicionais. Isso foi evidenciado com a ausência dos papéis relativos ao cuidado consigo próprio e com os outros, com a incorporação precoce de papéis de dominação sexual masculina e de trabalhador e pai, ou seja, deixar de ser criança e alcançar a condição de homem.OBJECTIVE: To analyze gender relations perceived by male adolescents and how they contribute to making them more vulnerable to pregnancy during adolescence.

    This study investigated how dissatisfaction with particular aspects of the body was associated with overall body dissatisfaction among male adolescents in Western and Asian cultures. One hundred and six Malaysian Malays, 55 Malaysian Chinese, 195 Chinese from China, and 45 non-Asian Australians aged 12 to 19 years completed a questionnaire assessing dissatisfaction with their overall body and dissatisfaction with varying aspects of their body. Dissatisfaction with the face, height, and hair was positively correlated with overall body dissatisfaction among Malaysian Malays after body mass index, age and dissatisfaction with body areas typically included in measures (weight/shape, upper, middle, and lower body, and muscles) had been controlled for. Dissatisfaction with the face was positively correlated with overall body dissatisfaction among Malaysian Chinese. These findings demonstrate the differences in body focus for males from different cultures and the importance of using assessment measures that address all possible areas of body focus.

    We investigated the relationship between three factors--internal/external locus of control, self-esteem, and parental verbal interaction--for at-risk Black male adolescents in the United States. Forty-two male students in Grades 6, 7, and 8 who had been identified by their teachers as being at risk completed the Locus of Control Scale for Children (Nowicki & Strickland, 1973), the Self-Esteem Inventory (Coopersmith, 1967), and the Verbal Interaction Questionnaire (Blake, 1991). A moderate positive relationship found between self-esteem and parental verbal interaction was consistent with a previous finding for White high school students. A moderate negative relationship found between locus of control and self-esteem differed from a previous finding of no significant relationship for Black elementary children. A weak, yet significant, negative relationship was found between locus of control and parental verbal interaction. PMID:8057628

    Full Text Available This article revealed the degree of trauma experienced by male adolescents when their fathers are absent. The cost of this absence could not be balanced with the material benefits the children have enjoyed, for the benefits have been outweighed by the trauma that children experience in the absence of their fathers. The emotions and tears expressed during the research journey have revealed that material support cannot compensate for the love and presence children expect from their fathers. The deep hurt instilled in their hearts by the periods of absence angered them and led to traumatic experiences. The protracted period of living with only one primary caregiver has imprisoned them into the feminised environment, thereby robbing them of a male identity. Therefore, this article was devoted to creating a shepherding model of caring for boys whose fathers are absent.

    Increased binge alcohol consumption has been reported among adolescents as compared to adults in both humans and rodent models, and has been associated with serious long-term health consequences. However, the neurochemical mechanism for age differences in binge drinking between adolescents and adults has not been established. The present study was designed to evaluate the mechanistic role of the cannabinoid CB1 receptor in adolescent and adult binge drinking. Binge consumption was established in adolescent and adult male C57BL/6J mice by providing access to 20% alcohol or 1% sucrose for 4 h every other day. Pretreatment with the CB1 antagonist/inverse agonist AM-251 (0, 1, 3, and 10 mg/kg) in a Latin square design dose-dependently reduced adolescent alcohol consumption to adult levels without altering adult intake. AM-251 (3 mg/kg) also reduced adolescent but not adult sucrose consumption. Adolescent reductions in alcohol and sucrose were not associated with alterations in open-field locomotor activity or thigmotaxis. These findings point to age differences in CB1 receptor activity as a functional mediator of adolescent-typical increased binge drinking as compared to adults. Developmental alterations in endocannabinoid signaling in the adolescent brain may therefore be responsible for the drinking phenotype seen in this age group. PMID:26800788

    Full Text Available Background: A role model is perceived as worthy of imitation, their selection can indicate significant elements of psychosocial health and self-projection in adolescents. Patterns of behavior and lifestyle choices established during adolescence can have immediate and lasting effects on health. Materials and Methods: Cross-sectional study was undertaken in the schools of Aligarh, Uttar Pradesh, India. The sample frame was 2347, out of which a sample of 390 students was studied. Data collected were entered and analyzed by SPSS for Windows version 10%. Results: Majority (62.7% of adolescents revealed that their role models were Film Star (34.8% and their Teachers (27.9%, Parents (14.3%, Sportsman (12.0%. Politicians as the role models were opted by least proportion (1.2%. Desire of future occupation was Businessmen (27.9%, Doctor (18.6, and Engineer (14.4%. Conclusion: Nearly all adolescents had a role model. There is greater impact of cinema on the minds of adolescents, which resulted in choosing film actors as their role model. Aspiration of future occupation was not related to the characteristics of the role model.

    Full Text Available Most smokers start young. Initiation of cigarette smoking at an earlier age leads to more life-years for tobacco use, makes quitting harder, and increases the risk of serious health consequences. Despite these challenges, research focusing on smoking behavior among adolescent boys in Taiwan is rare. Although the Taiwanese government enacted the Tobacco Hazards Prevention Act in 2009, aimed at prevention and reducing the rate of smoking, the percentage of high school students who smoke has continued to increase. In 2006, 7.5% of adolescent boys engaged in smoking. By 2012 the rate had increased to 24.6%. This paper explores the experiences that contribute to adolescent Taiwanese boys making the decision to smoke. A phenomenological approach to inquiry was used as the philosophical foundations for this study with twelve adolescent boys who engaged in smoking behaviors. Data was gathered through two face-to-face semi-structured interviews and a focus group. Data analysis was performed using Colaizzi’s analysis method. Findings indicated that decisions to begin smoking were motivated by curiosity and as a means of establishing friendships while decisions to continue smoking were linked to the addictive nature of smoking and as a means of coping with stress and passing the time. The findings can be used to inform the prevention of tobacco use and to reduce the high smoking rates among adolescent boys.

    2015-02-01

    This study aimed to examine the presence and impact of dynamic protective factors for delinquency in male adolescents with a history of sexual and/or violent offending. Bipolar factors (factors with risk and protective factors being the ends of the same continuum) were examined in male adolescents with a history of sexual offenses against younger children (CSOs; n = 341), a history of sexual offenses against peers and/or adult victims (PSOs; n = 207), and a history of nonsexual violent offenses (VOs; n = 1,356). We conducted secondary analyses on data collected with the Washington State Juvenile Court Assessment and on general recidivism data. ANOVA, correlations, Fisher's z tests, and logistic regression analyses were applied. Results showed that, in VOs, the number of risk factors was greater than the number of protective factors, whereas in PSOs, and especially CSOs, the number of protective factors was greater than the number of risk factors. Protective factors appeared to be especially important for juveniles with a history of sexual offenses for two reasons. First, the impact of most protective factors on recidivism was larger among juveniles with a history of sexual offenses than among those with a history of violent offenses. Second, protective factors added to the predictive accuracy over and above risk factors in juveniles with a history of sexual offenses, but not in those with a history of violent offenses.

  19. A Behavioral Measure of Costly Helping: Replicating and Extending the Association with Callous Unemotional Traits in Male Adolescents.

    Directory of Open Access Journals (Sweden)

    Joseph T Sakai

    Full Text Available Some conduct-disordered youths have high levels of callous unemotional traits and meet the DSM-5's "with limited prosocial emotions" (LPE specifier. These youths often do aggressive, self-benefitting acts that cost others. We previously developed a task, the AlAn's game, which asks participants to repeatedly decide whether to accept or reject offers in which they will receive money but a planned charity donation will be reduced. In our prior work, more "costly helping" (i.e., rejecting the offered money and protecting the donation was associated with lower callous unemotional traits. Here we extend that prior work in a larger sample of adolescent male patients with serious conduct problems and controls, and test whether this association is mediated specifically by a Moral Elevation response (i.e., a positive emotional response to another's act of virtue.The adolescent male participants were: 45 patients (23 with LPE and 26 controls, who underwent an extensive phenotypic assessment including a measure of Moral Elevation. About 1 week later participants played the AlAn's game.All AlAn's game outcomes demonstrated significant group effects: (1 money taken for self (p = 0.02; (2 money left in the charitable donation (p = 0.03; and, (3 costly helping (p = 0.047. Controls took the least money and did the most costly helping, while patients with LPE took the most money and did the least costly helping. Groups also significantly differed in post-stimulus Moral Elevation scores (p = 0.005. Exploratory analyses supported that the relationship between callous unemotional traits and costly helping on the AlAn's game may be mediated in part by differences in Moral Elevation.The AlAn's game provides a standardized behavioral measure associated with callous unemotional traits. Adolescents with high levels of callous unemotional traits engage in fewer costly helping behaviors, and those differences may be related to blunting of positive emotional responses.

    Background Acne vulgaris is a pilosebaceous follicle disorder affecting over 85% of adolescents to some degree. It frequently causes psychological distress that may persist into adulthood due to scarring. Little information about post-acne scarring epidemiology is available. Objectives To describe prevalence, distribution patterns and associated factors of acne scarring in young males, drawing on a representative population sample from a southern Brazilian city. Methods A cross-sectional study was undertaken during presentation for military service, which is compulsory for all 18-year-old males. A questionnaire was applied, covering topics like diet, smoking habits, ethnicity, family structure, socio-economic level, as well as specific questions about active acne and resulting scars. Dermatologists conducted the clinical examination. Results A total of 2,201 male adolescents were interviewed and examined. The overall prevalence of acne scarring was 22%. The malar region was the most frequently involved, present in 80% of affected individuals, followed by the frontal region (31.5%), back (17%), anterior chest (8.2%) and mentonian region (6.4%). Correlation between the intensity of clinical acne and the presence of scars was found, but no association was observed with educational level, smoking, ethnicity, obesity or socio-economic status. Conclusions There is a high prevalence of acne scars among this population. This is the first study to ascertain a correlation between acne scarring and factors such as socio-economic status and educational level. The direct relation between acne severity and scarring indicates that prompt and effective treatment is the best way to reduce scarring. PMID:27438194

    Full Text Available Adolescence is a period of major physical, hormonal and psychological change. It is also characterized by a significant increase in the incidence of psychopathologies and this increase is gender-specific. Likewise, stress during adolescence is associated with the development of psychiatric disorders later in life. Previously, using a rat model of psychogenic stress (exposure to predator odor followed by placement on an elevated platform during the pre-pubertal period (postnatal days 28-30, we reported sex-specific effects on auditory and contextual fear conditioning. Here, we study the short-term impact of psychogenic stress before and during puberty (postnatal days 28-42 on behavior (novelty seeking, risk taking, anxiety and depression and hypothalamus-pituitary-adrenocortical (HPA axis activation during late adolescence (postnatal days 45-51. Peri-pubertal stress decreased anxiety-like behavior and increased risk taking and novelty seeking behaviors during late adolescence (measured with the elevated plus maze, open field and exposure to novel object tests and intake of chocopop pellets before or immediate after stress. Finally neither depressive-like behavior (measured at the forced swim test nor HPA response to stress (blood corticosterone and glucose were affected by peri-pubertal stress. Nevertheless, when controlling for the basal anxiety of the mothers, animals exposed to peri-pubertal stress showed a significant decrease in corticosterone levels immediate after an acute stressor. The results from this study suggest that exposure to mild stressors during the peri-pubertal period induces a broad spectrum of behavioral changes in late adolescence, which may exacerbate the independence-building behaviors naturally happening during this transitional period (increase in curiosity, sensation-seeking and risk taking behaviors.

    2016-01-01

    Cancer represents the second cause of death in prepubertal children and adolescents, although it is currently associated with an overall survival rate of 80%–85%. The annual incidence rate is 186.6 per 1 million children and adolescents aged up to 19 years. Both disease and treatment options are associated with life-altering, long-term effects that require monitoring. Infertility is a common issue, and as such, fertility preservation represents an essential part in the management of young patients with cancer who are at risk of premature gonadal failure. This review deals with the up-to-date available data on fertility risk assessment and preservation strategies that should be addressed prior to antineoplastic therapy in this vulnerable subgroup of cancer patients.

    2016-06-01

    Using ecological theory and the peer socialization model, the current study identified risk and protective factors associated with internalizing and externalizing symptoms across ecological domains. It was hypothesized that the constellation of risk and protective factors within the peer microsystem would vary by gender: future optimism and negative peer influence were expected to be significant risk/protective factors for males, whereas peer victimization was expected to be significant risk factors among females. Using four waves of data, three-level hierarchical linear models were estimated for males and females. Results revealed that negative peer influence was a particularly salient risk factor for both internalizing and externalizing behaviors among males, although future optimism did not emerge as a significant protective factor. In addition, as hypothesized, peer victimization indicators were significant risk factors for females. Parent-child conflict was also significantly and positively associated with both internalizing and externalizing symptoms for males and females. Implications are discussed. PMID:26341092

    Background: As adolescents spend much time on playing computer games, their mental and social effects should be considered. The present study aimed to investigate the association between playing computer games and the mental and social health among male adolescents in Iran in 2014. Materials and Methods: This is a cross-sectional study conducted on 210 adolescents selected by multi-stage random sampling. Data were collected by Goldberg and Hillier general health (28 items) and Kiez social health questionnaires. The association was tested by Pearson and Spearman correlation coefficients, one-way analysis of variance (ANOVA), and independent t-test. Computer games related factors such as the location, type, length, the adopted device, and mode of playing games were investigated. Results: Results showed that 58.9% of the subjects played games on a computer alone for 1 h at home. Results also revealed that the subjects had appropriate mental health and 83.2% had moderate social health. Results showed a poor significant association between the length of games and social health (r = −0.15, P = 0.03), the type of games and mental health (r = −0.16, P = 0.01), and the device used in playing games and social health (F = 0.95, P = 0.03). Conclusions: The findings showed that adolescents’ mental and social health is negatively associated with their playing computer games. Therefore, to promote their health, educating them about the correct way of playing computer games is essential and their parents and school authorities, including nurses working at schools, should determine its relevant factors such as the type, length, and device used in playing such games.

    This study examined the applicability of the Psychopathy Checklist: Youth Version (PCL:YV; Forth, Kosson, & Hare, 2003) among a large sample of serious offending adolescent males. Adopting an item response theory approach, item properties of the PCL:YV were examined using the generalized partial credit model. Results showed that need for stimulation, "irresponsibility," and callous & unemotional were sensitive to changes in respondents' varying psychopathy levels, whereas lack of realistic, long-term goals; superficial charm; and revocation of conditional release were less so (quoted PCL:YV item published with permission by Multi-Health Systems, Inc.; see full permissions statement in footnote 1 in the article; other items are paraphrased). Substantial differential item functioning was also found in 15 of the 20 PCL:YV items among Caucasian, African American, and Hispanic offending boys, indicating that item functioning was not invariant across race/ethnicity. Questions remain regarding whether the construct of psychopathy as assessed with the PCL:YV is equivalent across adolescents in general and across different race/ethnic groups in particular.

    Behaviors associated with autism spectrum disorder (ASD) have been suggested to be considered as quantitative traits. This study investigated the structural and functional correlates of autistic traits measured using the Social Responsiveness Scale (SRS) in neurotypical adolescents. Twenty-six neurotypical male adolescents (12-18 years old) were recruited for this study and underwent structural and resting functional magnetic resonance image scanning, and intelligence quotient and SRS evaluations. We used the automated surface-based method (FreeSurfer) to measure cortical thickness and seed-based functional connectivity (FC) analysis to derive the FC map of the dorsal anterior cingulate (dACC). Brain-wise regression analyses of cortical thickness and FC maps on SRS scores were performed using a general linear model. The results indicated that higher autistic trait ratings of total SRS scores were associated with a thinner cortex in the left insula, right insula, and right superior temporal gyrus. Furthermore, we observed that only higher scores of social awareness were correlated with increased FC between the dACC and right superior temporal gyrus and decreased FC between the dACC and right putamen and thalamus. These results indicated that a quantitative trait in social cognition is associated with structural and connectivity variations linked to ASD patients.

    This study tested the predictive power of gaming versatility (i.e., the number of video game genres engaged in) on game addiction in male adolescents, controlling for time spent on gaming. Participants were 701 male adolescents attending high school (Mage=15.6 years). Analyses showed that pathological gaming was predicted not only by higher time spent on gaming, but also by participation in a greater number of video game genres. Specifically, the wider the array of video game genres played, the higher were the negative consequences caused by gaming. Findings show that versatility can be considered as one of the behavioral risk factors related to gaming addiction, which may be characterized by a composite and diversified experience with video games. This study suggests that educational efforts designed to prevent gaming addiction among youth may also be focused on adolescents' engagement in different video games. PMID:25684613

  11. Adolescent binge drinking leads to changes in alcohol drinking, anxiety, and amygdalar corticotropin releasing factor cells in adulthood in male rats.

    Nicholas W Gilpin

    Full Text Available Heavy episodic drinking early in adolescence is associated with increased risk of addiction and other stress-related disorders later in life. This suggests that adolescent alcohol abuse is an early marker of innate vulnerability and/or binge exposure impacts the developing brain to increase vulnerability to these disorders in adulthood. Animal models are ideal for clarifying the relationship between adolescent and adult alcohol abuse, but we show that methods of involuntary alcohol exposure are not effective. We describe an operant model that uses multiple bouts of intermittent access to sweetened alcohol to elicit voluntary binge alcohol drinking early in adolescence (~postnatal days 28-42 in genetically heterogeneous male Wistar rats. We next examined the effects of adolescent binge drinking on alcohol drinking and anxiety-like behavior in dependent and non-dependent adult rats, and counted corticotropin-releasing factor (CRF cell in the lateral portion of the central amygdala (CeA, a region that contributes to regulation of anxiety- and alcohol-related behaviors. Adolescent binge drinking did not alter alcohol drinking under baseline drinking conditions in adulthood. However, alcohol-dependent and non-dependent adult rats with a history of adolescent alcohol binge drinking did exhibit increased alcohol drinking when access to alcohol was intermittent. Adult rats that binged alcohol during adolescence exhibited increased exploration on the open arms of the elevated plus maze (possibly indicating either decreased anxiety or increased impulsivity, an effect that was reversed by a history of alcohol dependence during adulthood. Finally, CRF cell counts were reduced in the lateral CeA of rats with adolescent alcohol binge history, suggesting semi-permanent changes in the limbic stress peptide system with this treatment. These data suggest that voluntary binge drinking during early adolescence produces long-lasting neural and behavioral effects

    Human adolescents often consume alcohol in a binge-like manner at a time when changes are occurring within specific brain structures, such as the medial prefrontal cortex (mPFC) and the basolateral nucleus of the amygdala (BLN). In particular, the number of neurons and glia is changing in both of these areas in the rat between adolescence and adulthood (Markham et al., 2007; Rubinow and Juraska, 2009). The current study investigated the effects of ethanol exposure during adolescence on the number of neurons and glia in the adult mPFC and BLN in Long-Evans male and female rats. Saline or 3g/kg ethanol was administered between postnatal days (P) 35-45 in a binge-like pattern, with 2days of injections followed by 1 day without an injection. Stereological analyses of the ventral mPFC (prelimbic and infralimbic areas) and the BLN were performed on brains from rats at 100 days of age. Neuron and glia densities were assessed with the optical disector and then multiplied by the volume to calculate the total number of neurons and glia. In the adult mPFC, ethanol administration during adolescence resulted in a decreased number of glia in males, but not females, and had no effect on the number of neurons. Adolescent ethanol exposure had no effects on glia or neuron number in the BLN. These results suggest that glia cells in the prefrontal cortex are particularly sensitive to binge-like exposure to ethanol during adolescence in male rats only, potentially due to a decrease in proliferation in males or protective mechanisms in females.

    Full Text Available The relative importance of genetic and socio-cultural influences contributing to the success of east Africans in endurance athletics remains unknown in part because the pre-training phenotype of this population remains incompletely assessed. Here cardiopulmonary fitness, physical activity levels, distance travelled to school and daily energy expenditure in 15 habitually active male (13.9±1.6 years and 15 habitually active female (13.9±1.2 adolescents from a rural Nandi primary school are assessed. Aerobic capacity ([Formula: see text] was evaluated during two maximal discontinuous incremental exercise tests; physical activity using accelerometry combined with a global positioning system; and energy expenditure using the doubly labelled water method.

    Background Some conduct-disordered youths have high levels of callous unemotional traits and meet the DSM-5’s “with limited prosocial emotions” (LPE) specifier. These youths often do aggressive, self-benefitting acts that cost others. We previously developed a task, the AlAn’s game, which asks participants to repeatedly decide whether to accept or reject offers in which they will receive money but a planned charity donation will be reduced. In our prior work, more "costly helping" (i.e., rejecting the offered money and protecting the donation) was associated with lower callous unemotional traits. Here we extend that prior work in a larger sample of adolescent male patients with serious conduct problems and controls, and test whether this association is mediated specifically by a Moral Elevation response (i.e., a positive emotional response to another’s act of virtue). Methods The adolescent male participants were: 45 patients (23 with LPE) and 26 controls, who underwent an extensive phenotypic assessment including a measure of Moral Elevation. About 1 week later participants played the AlAn’s game. Results All AlAn’s game outcomes demonstrated significant group effects: (1) money taken for self (p = 0.02); (2) money left in the charitable donation (p = 0.03); and, (3) costly helping (p = 0.047). Controls took the least money and did the most costly helping, while patients with LPE took the most money and did the least costly helping. Groups also significantly differed in post-stimulus Moral Elevation scores (p = 0.005). Exploratory analyses supported that the relationship between callous unemotional traits and costly helping on the AlAn’s game may be mediated in part by differences in Moral Elevation. Conclusions The AlAn's game provides a standardized behavioral measure associated with callous unemotional traits. Adolescents with high levels of callous unemotional traits engage in fewer costly helping behaviors, and those differences may be related

    Full Text Available Abstract Background Increased risk of schizophrenia in adolescent males indicates that a link between the development of dopamine-related psychopathology and testosterone-driven brain changes may exist. However, contradictions as to whether testosterone increases or decreases dopamine neurotransmission are found and most studies address this in adult animals. Testosterone-dependent actions in neurons are direct via activation of androgen receptors (AR or indirect by conversion to 17β-estradiol and activation of estrogen receptors (ER. How midbrain dopamine neurons respond to sex steroids depends on the presence of sex steroid receptor(s and the level of steroid conversion enzymes (aromatase and 5α-reductase. We investigated whether gonadectomy and sex steroid replacement could influence dopamine levels by changing tyrosine hydroxylase (TH protein and mRNA and/or dopamine breakdown enzyme mRNA levels [catechol-O-methyl transferase (COMT and monoamine oxygenase (MAO A and B] in the adolescent male rat substantia nigra. We hypothesized that adolescent testosterone would regulate sex steroid signaling through regulation of ER and AR mRNAs and through modulation of aromatase and 5α-reductase mRNA levels. Results We find ERα and AR in midbrain dopamine neurons in adolescent male rats, indicating that dopamine neurons are poised to respond to circulating sex steroids. We report that androgens (T and DHT increase TH protein and increase COMT, MAOA and MAOB mRNAs in the adolescent male rat substantia nigra. We report that all three sex steroids increase AR mRNA. Differential action on ER pathways, with ERα mRNA down-regulation and ERβ mRNA up-regulation by testosterone was found. 5α reductase-1 mRNA was increased by AR activation, and aromatase mRNA was decreased by gonadectomy. Conclusions We conclude that increased testosterone at adolescence can shift the balance of sex steroid signaling to favor androgenic responses through promoting

    The aim of this study was to determine the physical development level of post-adolescent automotive repair workers who had been employed in heavy work during adolescence, a critical developmental period. Young workers (Group 1, N = 106, Mean age = 18.33, SD = 0.65) employed an average of 6 years in workshops in the capital of Turkey, Ankara. For the control group, two groups of the same age but having a difference in terms of socioeconomic status were chosen. The first one of these was comprised of individuals who had the same socioeconomic status as the laborers (Group 2, N = 106, Mean age = 18.33, SD = 0.65) but were not laborers. The second control group was composed of individuals from the higher socioeconomic levels of society (Group 3, N = 100, Mean Age = 18.45 SD = 0.63). Weight, height and measures were taken from the individuals and the body mass index (kg/m2) was calculated. The results of the analysis show that, although all the variables of the labor group were lower than Group 2, the difference is only significant for the height variable (p youngsters are prone to chronic developmental retardation.

    The theory of reasoned action (TRA) is one of the most common models in predicting health-related behaviors and is used more often in health education studies. This study aimed to add two control constructs (perceived behavioral control - PBC and self-efficacy - SE) to the TRA and compare them using the structural equation modeling (SEM) for substance use avoidance among Iranian male adolescents in order to find out which model was a better fit in predicting the intention. This was a cross-sectional study carried out in Tehran, Iran. Data were collected from a random sample of high school male students (15-19 years of age) using a questionnaire containing items related to the TRA plus items reflecting two additional constructs (SE and PBC). In all, 433 students completed the questionnaires. The results obtained from SEM indicated a better fit to the data for the TRA with SE compared to the TPB (TRA with PBC) and TRA (χ2/df=2.55, RMSEA=0.072, CFI=0.96, NFI=0.94, NNFI=0.95, SRMR=0.058). Comparing SE and PBC, the results showed that self-efficacy was a better control construct in improving the TRA and predicting substance use avoidance intention (41%). The TRA with SE had a better model fit than TPB and the original version of the TRA. PMID:25427059

    Scalp eruptions are common in infants, children, and adolescents and the etiology can be broad. Allergic contact dermatitis can result after multiple non eventful uses of a hair care product, including shampoo, relaxers, and coloring agents. Symptoms of allergic contact dermatitis include intense pruritus with weeping, pain, and stinging sensations. Signs on physical examination include swelling with scaly erythematous plaques as well as bullae with vesicles and pustules in severe cases. The forehead, eyelids, and postauricular areas also are subject to swelling. Definitive diagnosis of allergic dermatitis involves patch testing to determine the specific allergen. Education about avoidance of the allergen and recommendations for allergen-free products are the most important aspects of managing patients with allergic contact dermatitis. Treatment depends on the severity and extent of involvement. First-line treatment is topical corticosteroids, followed by topical calcineurin inhibitors. For more extensive dermatitis, systemic corticosteroids are beneficial. PMID:26527634

    Adolescent substance abuse is a serious public health concern, and in response to this problem, a number of effective treatment approaches have been developed. Despite this, retaining and engaging adolescents in treatment are 2 major challenges continuously faced by practitioners and clinical researchers. Low retention and engagement rates are especially salient for ethnic minority adolescents because they are at high risk for underutilization of substance abuse treatment compared to their White peers. Latino adolescents, in particular, are part of the fastest growing ethnic minority group in the United States and experience high rates of substance use disorders. Heretofore, the empirical examination of cultural factors that influence treatment retention and engagement has been lacking in the literature. The goal of this study was to investigate the influence of the cultural variables ethnic identity, familism, and acculturation on the retention and engagement of Latino adolescents participating in substance abuse treatment. This study used data collected from a sample of Latino adolescent males (N = 96), predominantly of Mexican descent, and largely recruited from the juvenile justice system. Analysis was conducted using generalized regression models for count variables. Results indicated that higher levels of exploration, a subfactor of ethnic identity, and familism were predictive of attendance and engagement. In contrast, higher levels of Anglo orientation, a subfactor of acculturation, were predictive of lower treatment attendance and engagement. Clinical implications for the variables of ethnic identity, acculturation, and familism as well as suggestions for future research are discussed. PMID:26168226

    Smoking initiation predominantly occurs during adolescence, often in the presence of peers. Therefore, understanding the neural mechanisms underlying the rewarding effects of nicotine and social stimuli is vital. Using the conditioned place preference (CPP) procedure, we measured immediate early gene (IEG) expression in animals following exposure either to a reward-conditioned environment or to the unconditioned stimuli (US). Adolescent, male rats were assigned to the following CPP US conditions: (1) Saline+Isolated, (2) Nicotine+Isolated, (3) Saline+Social, or (4) Nicotine+Social. For Experiment 1, brain tissue was collected 90min following the CPP expression test and processed for Fos immunohistochemistry. We found that rats conditioned with nicotine with or without a social partner exhibited CPP; however, we found no group differences in Fos expression in any brain region analyzed, with the exception of the nucleus accumbens core that exhibited a social-induced attenuation in Fos expression. For Experiment 2, brain tissue was collected 90min following US exposure during the last conditioning session. We found social reward-induced increases in IEG expression in striatal and amydalar subregions. In contrast, nicotine reduced IEG expression in prefrontal and striatal subregions. Reward interactions were also found in the dorsolateral striatum, basolateral amygdala, and ventral tegmental area where nicotine alone attenuated IEG expression and social reward reversed this effect. These results suggest that in general social rewards enhance, whereas nicotine attenuates, activation of mesocorticolimbic regions; however, the rewards given together interact to enhance activation in some regions. The findings contribute to knowledge of how a social environment influences nicotine effects. PMID:27435419

    Sexually explicit material (SEM) (including Internet, video, and print) may play a key role in the lives of Black same-sex sexually active youth by providing the only information to learn about sexual development. There is limited school- and/or family-based sex education to serve as models for sexual behaviors for Black youth. We describe the role SEM plays in the sexual development of a sample of Black same-sex attracted (SSA) young adolescent males ages 15-19. Adolescents recruited from clinics, social networking sites, and through snowball sampling were invited to participate in a 90-min, semi-structured qualitative interview. Most participants described using SEM prior to their first same-sex sexual experience. Participants described using SEM primarily for sexual development, including learning about sexual organs and function, the mechanics of same-gender sex, and to negotiate one's sexual identity. Secondary functions were to determine readiness for sex; to learn about sexual performance, including understanding sexual roles and responsibilities (e.g., "top" or "bottom"); to introduce sexual performance scripts; and to develop models for how sex should feel (e.g., pleasure and pain). Youth also described engaging in sexual behaviors (including condom non-use and/or swallowing ejaculate) that were modeled on SEM. Comprehensive sexuality education programs should be designed to address the unmet needs of young, Black SSA men, with explicit focus on sexual roles and behaviors that may be inaccurately portrayed and/or involve sexual risk-taking (such as unprotected anal intercourse and swallowing ejaculate) in SEM. This work also calls for development of Internet-based HIV/STI prevention strategies targeting young Black SSA men who may be accessing SEM. PMID:25677334

    Commonly used dating violence prevention programs assume that promotion of more egalitarian gender role attitudes will prevent dating violence perpetration. Empirical research examining this assumption, however, is limited and inconsistent. The current study examined the longitudinal association between gender role attitudes and physical dating violence perpetration among adolescent boys (n = 577; 14 % Black, 5 % other race/ethnicity) and examined whether injunctive (i.e., acceptance of dating violence) and descriptive (i.e., beliefs about dating violence prevalence) normative beliefs moderated the association. As expected, the findings suggest that traditional gender role attitudes at T1 were associated with increased risk for dating violence perpetration 18 months later (T2) among boys who reported high, but not low, acceptance of dating violence (injunctive normative beliefs) at T1. Descriptive norms did not moderate the effect of gender role attitudes on dating violence perpetration. The results suggest that injunctive norms and gender role attitudes work synergistically to increase risk for dating violence perpetration among boys; as such, simultaneously targeting both of these constructs may be an effective prevention approach.

    Adherence to antiretroviral therapy (ART) is crucial for thwarting HIV disease progression and reducing secondary HIV transmission, yet youth living with HIV (YLH) struggle with adherence. The highest rates of new HIV infections in the United States occur in young African American men. A sample of 387 HIV-positive young African American males on ART was selected from a cross-sectional assessment of (YLH) receiving medical care within the Adolescent Trials Network for HIV/AIDS Interventions (ATN) from 2010 to 2012 (12-24 years old, median 22.00, SD 2.08). Participants completed self-reported adherence, demographic, health, and psychosocial measures. Sixty-two percent self-reported 100% ART adherence. Optimal data analysis identified frequency of cannabis use during the past 3 months as the strongest independent predictor of adherence, yielding moderate effect strength sensitivity (ESS) = 27.1, p cannabis use, 72% reported full adherence; in contrast, only 45% of participants who used cannabis frequently reported full adherence. Classification tree analysis (CTA) was utilized to improve classification accuracy and to identify the pathways of ART adherence and nonadherence. The CTA model evidenced a 38% improvement above chance for correctly classifying participants as ART adherent or nonadherent. Participants most likely to be adherent were those with low psychological distress and minimal alcohol use (82% were adherent). Participants least likely to be adherent were those with higher psychological distress and engaged in weekly cannabis use (69% were nonadherent). Findings suggest multiple profiles of ART adherence for young African American males living with HIV and argue for targeted psychosocial interventions. PMID:27410496

    Seventy-five 14-18-year-old gay, bisexual, and queer (GBQ) males provided feedback about how their participation in national, online focus groups (FG) about GBQ sexual health related topics resulted in behavioral and attitudinal changes. Most sexually experienced youth agreed that their participation positively changed their views and behavioral intentions. Some said that being in the FG made them more comfortable talking about sex, their sexuality, and making safer choices such as negotiating condoms. Others indicated intentions to become more involved in the LGBT community. Sexually inexperienced FG participants similarly said that the FG discussion positively affected them-most commonly by reducing their sense of isolation as young GBQ men who were waiting to have sex. Many also thought that they would become more vocal advocates of abstinence and/or safe sex. Online FGs and facilitated discussion boards should be further explored as a low-cost HIV prevention program for GBQ youth. PMID:25490735

    The pubertal surge in gonadal hormones that occurs during adolescence may impact the long-term effects of early alcohol exposure and sex differences in drinking behavior in adulthood. We investigated this hypothesis by performing sham or gonadectomy surgeries in Long Evans rats around postnatal day (P) 20. From P35–45, males and females were given saline or 3.0 g/kg ethanol using a binge-like model of exposure (8 injections total). As adults (P100), they were trained to self-administer ethanol via a sucrose-fading procedure and then given access to different unsweetened concentrations (5–20% w/v) for 5 days/concentration. We found that during adolescence, ethanol-induced intoxication was similar in males and females that underwent sham surgery. In gonadectomized males and females, however, the level of intoxication was greater following the last injection compared to the first. During adulthood, females drank more sucrose per body weight than males and binge-like exposure to ethanol reduced sucrose consumption in both sexes. These effects were not seen in gonadectomized rats. Ethanol consumption was higher in saline-exposed females compared to males, with gonadectomy reversing this sex difference by increasing consumption in males and decreasing it in females. Exposure to ethanol during adolescence augmented ethanol consumption in both sexes, but this effect was statistically significant only in gonadectomized females. Together, these results support a role for gonadal hormones during puberty in the short- and long-term effects of ethanol on behavior and in the development of sex differences in consummatory behavior during adulthood.

    Body dissatisfaction is particularly prevalent during adolescence and has recently been linked to stress in females and males. However, prospective studies are needed to better understand the relationship between stress and body dissatisfaction. The present study investigates the direction of this association and the mediating role of self-esteem and body image importance. A sample of 298 adolescent females and males in Grades 7 to 10 (ages 12 to 17 years) were surveyed at two time points over a one-year period. Hierarchical regression analyses revealed that stress significantly predicted body dissatisfaction one year later. Furthermore, a multiple mediation analysis controlling for gender revealed a significant indirect effect in both cross-sectional and longitudinal models, indicating that stress predicts reductions in self-esteem and increases in body importance, which in turn predict body dissatisfaction. These findings suggest that stress, self-esteem, and body importance should be included in programmes aimed at improving body dissatisfaction. PMID:23993480

    Young men who have sex with men have the highest rates of new HIV infections in the U.S., but they have been understudied relative to other populations. As a formative step for the development of a text messaging HIV prevention intervention, this mixed methods study aimed to understand how adolescent gay and bisexual males (AGBM) make decisions about condom use and factors that may differ based on age, sexual experience, and rural versus urban residency. Four online, asynchronous focus groups were conducted with 75 14-18 year old AGBM across the U.S. Qualitative analyses uncovered themes related to relationship influences on condom use (e.g. marriage, trust), access issues, and attitudes and experiences that both encouraged as well as discouraged condom use. Mixed methods analyses explored differences between groups in endorsement of themes. For example, younger and sexually experienced participants were more likely to report the cost of condoms was prohibitive and sexually experienced and rural youth were more likely to describe being influenced by emotional aspects of the relationship. These data highlight both opportunities for as well as the importance of tailoring HIV prevention programs for sub-groups of AGBM. PMID:24906532

    Early life stressful events have detrimental effects on the brain and behavior, which are associated with the development of depression. Immune-inflammatory responses have been reported to contribute in the pathophysiology of depression. Many studies have reported on the beneficial effects of exercise against stress. However, underlying mechanisms through which exercise exerts its effects were poorly studied. Therefore, it applied maternal separation (MS), as a valid animal model of early-life adversity, in rats from postnatal day (PND) 2 to 14 for 180min per day. At PND 28, male Wistar albino rats were subjected to 5 experimental groups; 1) controls 2) MS rats 3) MS rats treated with fluoxetine 5mg/kg to PND 60, 4) MS rats that were subjected to voluntary running wheel (RW) exercise and 5) MS rats that were subjected to mandatory treadmill (TM) exercise until adulthood. At PND 60, depressive-like behaviors were assessed by using forced swimming test (FST), splash test, and sucrose preference test (SPT). Our results revealed that depressive-like behaviors following MS stress were associated with an increase in expression of toll-like receptor 4 (Tlr-4) and its main signaling protein, Myd88, in the hippocampal formation. Also, we found that voluntary (and not mandatory) physical exercise during adolescence is protected against depressant effects of early-life stress at least partly through mitigating the innate immune responses in the hippocampus.

    A number of studies have revealed that low birth weight children have a heightened risk of various maladaptive outcomes, including academic challenges and delinquent involvement. However, very little research to date has examined whether the relationship between low birth weight, poor academic performance, and delinquent peer affiliation is moderated by genetic risk. Using data from the National Longitudinal study of Adolescent Health, the present study examines whether male adolescents born at very low birth weights are significantly predisposed to poor academic performance and delinquent peer affiliation. Moreover, we test whether the effect of birth weight on these outcomes is conditioned by level of genetic risk. We find no evidence that very low birth weight males are more likely to affiliate with delinquent peers or perform poorly in school during adolescence. However, upon examining gene-environment interactions, we find that being born at a very low birth weight does significantly increase the odds of poor academic performance and delinquent peer affiliation among males who possess a higher level of genetic risk. Limitations are noted and the implications of the findings are discussed. PMID:25145687

    Using a large sample of adjudicated delinquent male youth (N = 696), we compared data from youth who had been adjudicated for sexually aggressive crimes and those who had been adjudicated for nonsexual offenses on eating dysfunction, body disapproval, history of sexual abuse, and pornography exposure. The sample included 526 (75.8%) youth adjudicated for sexual offenses and 170 (24.4%) youth adjudicated for nonsexual crimes. The average age of the sample was 16.8 years (SD = 1.6), and approximately half of the sample (47.7%, n = 310) self-identified as White. The results of hierarchical multiple regressions indicated that sexually aggressive youth scored significantly higher than nonsexually offending youth on both eating dysfunction and body disapproval measures. Pornography exposure and substance use predicted body disapproval and eating dysfunction in the entire sample of adjudicated youth. History of sexual abuse was a significant predictor of body disapproval in all adjudicated youth but was not a significant predictor of eating dysfunction. Implications for research and practice are offered. PMID:26701282

    A case of lymphoepithelial carcinoma (LEC) occurring in right submandibular gland of a 13-year-old Indian male is presented, wherein the lesion unveiled itself only after multiple fine needle aspiration (FNA) procedures. This unusual neoplasm has high frequency of occurrence in Eskimos and a predilection for the parotid gland. The aspirates obtained were highly cellular comprising tight clusters of atypical epithelial cells with admixture of lymphocytes. Histopathological examination of the resected submandibular gland and lymph node chain was consistent with the diagnosis of LEC. Immunohistochemistry (IHC) revealed cytokeratin (CK)-positive and S-100-negative tumor cells lying admixed with CD45-positive lymphoid cells. A detailed otorhinolaryngological examination with inclusion of multiple biopsies was found negative for any primary tumor. Although histopathological features of this entity are well established, only a handful of case reports describing cytological features of this entity are present in medical literature. We conclude that the cytomorphological features of LEC are sufficiently distinctive to at least, suggest a possibility of this lesion. PMID:23112470

    A common pattern in dominance hierarchies is that some ranks result in higher levels of psychosocial stress than others. Such stress can lead to negative health outcomes, possibly through altered levels of stress hormones. The dominance rank-stress physiology relationship is known to vary between species; sometimes dominants show higher levels of glucocorticoid stress hormones, whereas in other cases subordinates show higher levels. It is less clear how this relationship varies between groups of different ages or cultures. In this study, we used long-term cortisol measurement methods to compare the effect of rank on cortisol levels in adult and adolescent male rhesus macaques. In the adult groups, subordinates had significantly higher cortisol levels. In the adolescents, no significant correlation between cortisol and status was found. Further analysis demonstrated that the adult hierarchy was stricter than that of the adolescents. Adult subordinates received extreme aggression more frequently than dominants, and this class of behavior was positively correlated with cortisol; by contrast, adolescents showed neither trend. Together, these findings provide evidence for a cortisol-rank relationship determined by social factors, namely, despotism of the group, and highlight the importance of group-specific social analysis when comparing or combining results obtained from different groups of animals.

    Full Text Available Abstract Background In the Netherlands, youths of Moroccan origin account for a disproportionately large percentage of the population in juvenile justice institutions. Previous research showed that Moroccan adolescents in pre-trial arrest are characterized by less serious offending behavior (i.e., primarily property-based and lower levels of mental health problems than native Dutch adolescents in pre-trial arrest. To date, little is known about the parent-child relationship of these adolescents. This study examines the mother-son relationships of Moroccan and native Dutch delinquent adolescents and their association with adolescent delinquency. Methods In the present study, differences in the mother-son relationship characteristics between families of incarcerated (N = 129 and non-incarcerated (N = 324 adolescents were examined, and it was analyzed if these differences between incarcerated and non-incarcerated adolescents were the same for Moroccans and native Dutch. Data collection for the incarcerated sample took place from 2006 to 2008. Comparison data were used of interviews conducted with mothers originating from former larger studies in the general Dutch population. Latent Class Analysis was performed in order to identify types of mother-son relationship. Logistic regression analyses were used to identify the relationships between mother-son relationship types, incarceration and ethnicity. Results A three class model of mother-son relationship types was found: a low-conflict mother-son relationship type, a high-conflict mother-son relationship type, and a neglectful mother-son relationship type. Compared to the native Dutch adolescents, Moroccans (both in the incarcerated and non-incarcerated population more often showed a neglectful mother-son relationship type. For Moroccans, no differences in mother-son relationship types were found between the incarcerated and non-incarcerated adolescents, whereas considerable differences occurred

Methods: High-risk adolescent males with and without CD were compared on intellectual efficiency, cognitive flexibility, impulsivity, alexithymia, and cognitive coping strategies. Substance use was controlled for in analyses. Results: Both groups showed normal intellectual efficiency and cognitive flexibility, as well as heightened alexithymia and behavioral impulsivity. Youths with CD evidenced more self-defeating and black-and-white thinking under stress, and more acting-out under negative affect, than those without CD. Conclusions: Deficits specific to CD resided in facets of emotional functioning and cognitive coping that might be targeted by a coping skills intervention.

    Full Text Available BACKGROUND: Epidemiological data from South Africa demonstrate that risk of human immunodeficiency virus (HIV infection in males increases dramatically after adolescence. Targeting adolescent HIV-negative males may be an efficient and cost-effective means of maximising the established HIV prevention benefits of voluntary medical male circumcision (VMMC in high HIV prevalence-, low circumcision practice-settings. This study assessed the feasibility of recruiting male high school students for VMMC in such a setting in rural KwaZulu-Natal. METHODS AND FINDINGS: Following community and key stakeholder consultations on the acceptability of VMMC recruitment through schools, information and awareness raising sessions were held in 42 high schools in Vulindlela. A three-phase VMMC demand-creation strategy was implemented in partnership with a local non-governmental organization, ZimnadiZonke, that involved: (i community consultation and engagement; (ii in-school VMMC awareness sessions and centralized HIV counselling and testing (HCT service access; and (iii peer recruitment and decentralized HCT service access. Transport was provided for volunteers to the Centre for the AIDS Programme of Research in South Africa (CAPRISA clinic where the forceps-guided VMMC procedure was performed on consenting HIV-negative males. HIV infected volunteers were referred to further care either at the CAPRISA clinic or at public sector clinics. Between March 2011 and February 2013, a total of 5165 circumcisions were performed, the majority (71% in males aged between 15 and 19 years. Demand-creation strategies were associated with an over five-fold increase in VMMC uptake from an average of 58 procedures/month in initial community engagement phases, to an average of 308 procedures/month on initiation of the peer recruitment-decentralized service phase. Post-operative adverse events were rare (1.2%, mostly minor and self-resolving. CONCLUSIONS: Optimizing a high volume

    Full Text Available In recent years substance use has increased greatly throughout the world. Adolescence is the critical period when the first initiation of substance use takes place. Interventions at the adolescent age are effective to bring about lifestyle modifications. A community-based, cross-sectional study was carried out among 260 randomly selected adolescents in an urban slum area, with the objective of studying the prevalence and determinants of substance use among adolescents. The adolescent age group was selected as defined by the World Health Organization (WHO (10 - 19 years. The overall prevalence of substance use was 32.7%. About 31% initiated substance use at 13 - 15 years of age, and the reason was peer pressure in 52.9%. Education of the study subject, education of parents, and substance use by parents and by peers were significantly associated with substance use. Children and parents should be educated to prevent substance use. There was a need to change the social environment.

    Accumulating evidence suggests that rates of low bone mass are greater in HIV-infected males than females. Of 11 biomarkers assessed by sex and HIV-status, HIV-infected males had increased levels of soluble CD14 which inversely correlated with bone mineral content and bone mineral density measures, suggesting macrophage activation as a possible mechanism of differential bone loss.

    Although reduced cortisol reactivity to stress and increased circulating testosterone level are hypothesized to be associated with higher levels of externalizing behavior, empirical findings are inconsistent. One factor that may account for the heterogeneity in these relationships is prenatal testosterone exposure. This study examined whether the second-to-fourth digit ratio (2D:4D), a putative marker of prenatal testosterone exposure, moderates the relationships of testosterone and cortisol reactivity with externalizing behavior. Left and right hand 2D:4D and self-reported externalizing behavior were measured in a sample of 353 young adolescents (M age=11.92 years; 178 females; 79.7% African American). Saliva samples were collected before and after a stress task and later assayed for cortisol. Testosterone levels were determined from an AM saliva sample. 2D:4D interacted with cortisol reactivity to predict externalizing behavior in males, but not females. In males, low cortisol reactivity was associated with higher levels of aggression and rule-breaking behavior, but only among subjects with low 2D:4D (i.e., high prenatal testosterone). Findings suggest the importance of a multi-systems approach in which interactions between multiple hormones are taken into account. Furthermore, results demonstrate the importance of considering the organizational influence of prenatal testosterone in order to understand the activational influence of circulating hormones during adolescence.

    Full Text Available AIMS: To contribute new evidence to the controversy about the factor structure of the Eating Disorder Examination Questionnaire (EDE-Q and to provide, for the first time, norms based on a large adolescent Mexican community sample, regarding sex and area of residence (urban/rural. METHODS: A total of 2928 schoolchildren (1544 females and 1384 males aged 11-18 were assessed with the EDE-Q and other disordered eating questionnaire measures. RESULTS: Confirmatory factor analysis of the attitudinal items of the EDE-Q did not support the four theorized subscales, and a two-factor solution, Restraint and Eating-Shape-Weight concern, showed better fit than the other models examined (RMSEA = .054; measurement invariance for this two-factor model across sex and area of residence was found. Satisfactory internal consistency (ω ≥ .80 and two-week test-retest reliability (ICCa ≥ .84; κ ≥ .56, and evidence for convergent validity with external measures was obtained. The highest attitudinal EDE-Q scores were found for urban females and the lowest scores were found for rural males, whereas the occurrence of key eating disorder behavioural features and compensatory behaviours was similar in both areas of residence. CONCLUSIONS: This study reveals satisfactory psychometric properties and provides population norms of the EDE-Q, which may help clinicians and researchers to interpret the EDE-Q scores of adolescents from urban and rural areas in Mexico.

    Full Text Available Increased propensity for risky behavior in adolescents, particularly in peer groups, is thought to reflect maturational imbalance between reward processing and cognitive control systems that affect decision-making. We used functional magnetic resonance imaging (fMRI to investigate brain functional correlates of risk-taking behavior and effects of peer influence in 18-19-year-old male adolescents. The subjects were divided into low and high risk-taking groups using either personality tests or risk-taking rates in a simulated driving task. The fMRI data were analyzed for decision-making (whether to take a risk at intersections and outcome (pass or crash phases, and for the influence of peer competition. Personality test-based groups showed no difference in the amount of risk-taking (similarly increased during peer competition and brain activation. When groups were defined by actual task performance, risk-taking activated two areas in the left medial prefrontal cortex (PFC significantly more in low than in high risk-takers. In the entire sample, risky decision-specific activation was found in the anterior and dorsal cingulate, superior parietal cortex, basal ganglia (including the nucleus accumbens, midbrain, thalamus, and hypothalamus. Peer competition increased outcome-related activation in the right caudate head and cerebellar vermis in the entire sample. Our results suggest that the activation of the medial (rather than lateral PFC and striatum is most specific to risk-taking behavior of male adolescents in a simulated driving situation, and reflect a stronger conflict and thus increased cognitive effort to take risks in low risk-takers, and reward anticipation for risky decisions, respectively. The activation of the caudate nucleus, particularly for the positive outcome (pass during peer competition, further suggests enhanced reward processing of risk-taking under peer influence.

    Stressful early life experiences are implicated in lifelong health. However, little is known about the consequences of emotional stress (ES) or physical stress (PS) on neurobiology. Therefore, the following set of experiments was designed to assess changes in transcription and translation of key proteins within the nucleus accumbens (NAc). Male adolescent (postnatal day 35) or adult (8-week-old) mice were exposed to ES or PS using a witness social defeat paradigm. Then, 24 h after the last stress session, we measured levels of specific mRNAs and proteins within the NAc. Spine density was also assessed in separate groups of mice. Exposure to ES or PS disrupted extracellular signal-related kinase 2 (ERK2), reduced transcription of ΔFosB and had no effect on cAMP response element-binding protein (CREB) mRNA. Western blots revealed that exposure to ES or PS decreased ERK2 phosphorylation in adolescents, whereas the same stress regimen increased ERK2 phosphorylation in adults. Exposure to ES or PS had no effect on ΔFosB or CREB phosphorylation. ES and PS increased spine density in the NAc of adolescent exposed mice, but only exposure to PS increased spine density in adults. Together, these findings demonstrate that exposure to ES or PS is a potent stressor in adolescent and adult mice and can disturb the integrity of the NAc by altering transcription and translation of important signaling molecules in an age-dependent manner. Furthermore, exposure to ES and PS induces substantial synaptic plasticity of the NAc. PMID:24943326

    Full Text Available Our study investigates the prevalence, patterns and predictors of tobacco smoking among early adolescent males in Northern Jordan and whether asthma diagnosis affects smoking patterns. A descriptive cross sectional design was used. Males in grades 7 and 8 from four randomly selected high schools in the city of Irbid were enrolled. Data on waterpipe (WP use and cigarette smoking patterns were obtained (n = 815 using a survey in Arabic language. The overall prevalence of ever having smoked a cigarette was 35.6%, with 86.2% of this group smoking currently. Almost half of the sample reported WP use. The most common age in which adolescents started to experiment with cigarettes was 11–12 years old (49.1%, although 10 years was also common (25.3%. Significant predictors of male cigarette smoking were WP use (OR = 4.15, 95% CI = 2.99–5.76, asthma diagnosis (OR = 2.35, 95% CI = 1.46–3.78, grade 8 (OR = 1.52, 95% CI = 1.10–2.11, and having a sibling who smokes (OR = 2.23, 95% CI = 1.53–3.24. However, this cross-sectional study cannot establish causality, thus longitudinal studies are needed. Public health programs and school-based anti-tobacco smoking interventions that target children in early years at high schools are warranted to prevent the uptake of tobacco use among this vulnerable age group. High school students with asthma should be specifically targeted.

    Binge drinking ethanol exposure during adolescence can lead to long-term neurobehavioural damage. It is not known whether the pubertal surge in testosterone that occurs during adolescence might impact the neurobehavioural effects of early ethanol exposure in adult animals. We examined this hypothesis by performing sham or gonadectomy surgeries on Sprague-Dawley rats around postnatal day (P) 23. From P28-65,the rats were administered 3.0g/kg ethanol using a binge-like model of exposure. Dependent measurements included tests of open field behaviour, blood ethanol concentrations, and testosterone levels. As adults, significant decreases in open field activity were observed in the GX rats. The open field behaviour of the GX rats was restored after testosterone administration. Binge-like ethanol exposure altered most of the parameters of the open field behaviour, suggestive of alcohol-induced anxiety, but rats treated with alcohol in combination with gonadectomy showed less motor behaviour and grooming behaviour and an increase in immobility, suggesting ethanol-induced depression. These results indicated that testosterone is required for ethanol-induced behavioural changes and that testicular hormones are potent stimulators of ethanol-induced behaviours. PMID:26238258

    Increased awareness of the importance of fertility concerns to teenage cancer survivors is leading to growing numbers of male teenagers being offered sperm banking at the time of diagnosis. This is now extending to males diagnosed with other conditions where gonadotoxic agents are used in treatment. The storage of sperm in these circumstances is a challenging aspect of health care, given the complex issues and timescale involved. UK law has been enacted to protect legal minors from the potentially harmful effects of exposure to pornographic materials, yet there is reason to suppose that their use in this context could have therapeutic benefit in aiding successful masturbation. This paper uses material gained through consultation with the eleven largest UK sperm banks and 94 male teenage cancer survivors, to discuss the associated legal and ethical dilemmas, including those around the role of parents/carers. Findings suggest that there is variable practice in sperm banks, that almost a quarter of teenage males wanted access to soft porn when banking sperm, and half wanted to bring in their own materials. It concludes that there is an urgent need for any legal barriers to the therapeutic use of pornographic materials to be understood and examined. PMID:17786648

    The effects of devices emitting electromagnetic field (EMF) on human health have become the subject of intense research among scientists due to the rapid increase in their use. Children and adolescents are particularly attracted to the use of devices emitting EMF, such as mobile phones. The aim of this study was therefore to investigate changes in the spinal cords of male rat pups exposed to the effect of 900MHz EMF. The study began with 24 Sprague-Dawley male rats aged 3 weeks. Three groups containing equal numbers of rats were established-control group (CG), sham group (SG) and EMF group (EMFG). EMFG rats were placed inside an EMF cage every day between postnatal days (PD) 21 and 46 and exposed to the effect of 900MHz EMF for 1h. SG rats were kept in the EMF cage for 1h without being exposed to the effect of EMF. At the end of the study, the spinal cords in the upper thoracic region of all rats were removed. Tissues were collected for biochemistry, light microscopy (LM) and transmission electron microscopic (TEM) examination. Biochemistry results revealed significantly increased malondialdehyde and glutathione levels in EMFG compared to CG and SG, while SG and EMFG catalase and superoxide dismutase levels were significantly higher than those in CG. In EMFG, LM revealed atrophy in the spinal cord, vacuolization, myelin thickening and irregularities in the perikarya. TEM revealed marked loss of myelin sheath integrity and invagination into the axon and broad vacuoles in axoplasm. The study results show that biochemical alterations and pathological changes may occur in the spinal cords of male rats following exposure to 900MHz EMF for 1h a day on PD 21-46. PMID:26708410

    Full Text Available This article relates to the primary study which aimed at addressing uncertainties about the type and nature of the relationship between the human immunodeficiency virus (HIV and acquired immune deficiency syndrome (AIDS and adolescent male orphans affected by this disease and all its aspects, such as poverty, exposure to crime and stigmatisation, and the lack of parental figures – more specifically, the absence of the father figure. Subsequently, this study aimed at dissecting the orphan’s life experiences in the midst of HIV and AIDS and explored ways in which these experiences influence his sexual and power relations with women and his role as future father and husband in the absence of a father figure (or male role model. Moreover, the researcher explored ways in which these past and future narratives influence or affect the male orphan’s view of and relationship with God, or whether it is rather this view of and relationship with God that influence and affect his relationship with his past narrative and writing of his future narratives. Research methods from the qualitative and case study research design and, more specifically, from postfoundational practical theology and narrative therapy, were employed in exploring the above issues. With the use of the metaphor of Tree of Life and the David narrative, the researcher journeyed with the co-researchers in the construction of a preferred alternative narrative, which in turn functions as a guiding metaphor for aspiring to the future and living their lives in a preferred and satisfying manner. Therefore this article explains the use of these metaphors during the seven movements of Postfoundational Practical Theology and shows how these metaphors succeeded in assisting the co-researchers with externalising aspects of their problem-saturated narratives, identifying unique outcomes amidst these narratives, and developing alternative narratives that serve as a vehicle for change and creating

    Incarcerated populations have an estimated incidence of intellectual disabilities (IDs) far higher than national norms, ranging as high as 10%. In the present study, the relation between ID and violence exposure in 115 incarcerated adolescents was examined. Interpersonal violence exposure (IPV-E) predicted an average decrease in full scale IQ of 4.5 points, explaining approximately 5% of the difference in IQ. Child maltreatment increased the odds of having a verbal disability by three folds and explained 17% of the variance in verbal disability. Hierarchical regression was used to examine the relative contribution of ethnicity, poverty, and violence exposure to intellectual functioning. The literature on racial bias in incarceration and the implications for the present study are discussed. PMID:21882671

    Numerous basic and epidemiological studies have connected prenatal maternal immune activation with the occurrence of schizophrenia and/or autism. Depending on subtle differences in protocols of the used animal model, a variety of behavioral abnormalities has been reported. This study investigated behavioral differences in Wistar rat offspring of both genders, exposed to the 100 μg/kg per day dose of lipopolysaccharide (LPS) in late embryogenesis (embryonic days 15 and 16), while tested at their adolescent and young adult age (postnatal days 40 and 60, respectively). Immune activation was confirmed by detecting high levels of TNF-α and IL-6 in dam blood withdrawn 2h after the first dose of LPS. The animals were assessed in three consecutive trials of locomotor activity (novelty exploration, response to i.p. saline injection and challenge with 0.5mg/kg amphetamine), Morris water maze and social interaction tests. Overt behavioral dysfunction was perceived in adult rats only, and these changes were gender-distinctive. When compared with control rats, LPS females displayed baseline hypolocomotion and a decreased reactivity to amphetamine, while LPS males exhibited spatial learning (acquisition trials) and memory (probe trial) impairments. Prenatal treatment did not affect the time spent in social interaction. As maternal exposure to LPS in late gestation resulted in behavioral changes in offspring in early adulthood, it may model schizophrenia-like, but not autism-like endophenotypes. However, lack of a potentiated response to amphetamine testified that this model could not mimic positive symptoms, but rather certain traits of cognitive dysfunction and deficit symptoms, in males and females, respectively.

    Cranial magnetic resonance (MR) imaging was performed in 124 male patients (aged 7-19 years), from 14 institutions, in whom a diagnosis of moderate to severe hemophilia was made. Blood tests in all subjects were negative for human immunodeficiency virus. Findings in MR studies were abnormal in 25 (20.2%) subjects. Six lesions in five subjects were classified as congenital. The most commonly identified congenital lesion was a posterior fossa collection of cerebrospinal fluid (five cases). Twenty-two subjects had acquired lesions that were probably related to the hemophilia or its treatment. The most commonly acquired lesions were single- or multifocal areas of high signal intensity within the white matter on T2-weighted images noted in 14 (11.3%) subjects. Two subjects had large focal areas of brain atrophy, and six had some degree of diffuse cerebral cortical atrophy. Three subjects (2.4%) had hemorrhagic lesions. To the authors' knowledge, the unexpected finding of small, focal, nonhemorrhagic white matter lesions has not previously been reported. PMID:1410372

    Near-infrared spectroscopy has long been used to measure tissue-specific O2 dynamics in exercise, but most published data have used continuous wave devices incapable of quantifying absolute Hemoglobin (Hb) concentrations. We used time-resolved near-infrared spectroscopy to study exercising muscle (Vastus Lateralis, VL) and prefrontal cortex (PFC) Hb oxygenation in 11 young males (15.3 ± 2.1 yrs) performing incremental cycling until exhaustion (peak VO2 = 42.7 ± 6.1 ml/min/kg, mean peak power = 181 ± 38 W). Time-resolved near-infrared spectroscopy measurements of reduced scattering (μs´) and absorption (μa) at three wavelengths (759, 796, and 833 nm) were used to calculate concentrations of oxyHb ([HbO2]), deoxy Hb ([HbR]), total Hb ([THb]), and O2 saturation (stO2). In PFC, significant increases were observed in both [HbO2] and [HbR] during intense exercise. PFC stO2% remained stable until 80% of total exercise time, then dropped (-2.95%, p = .0064). In VL, stO2% decreased until peak time (-6.8%, p = .01). Segmented linear regression identified thresholds for PFC [HbO2], [HbR], VL [THb]. There was a strong correlation between timing of second ventilatory threshold and decline in PFC [HbO2] (r = .84). These findings show that time-resolved near-infrared spectroscopy can be used to study physiological threshold phenomena in children during maximal exercise, providing insight into tissue specific hemodynamics and metabolism.

    Human adolescents often consume alcohol in a binge-like manner at a time when changes are occurring within specific brain structures, such as the medial prefrontal cortex (mPFC) and the basolateral nucleus of the amygdala (BLN). In particular, neuron and glia number are changing in both of these areas in the rat between adolescence and adulthood (Markham et al., 2007; Rubinow and Juraska, 2009). The current study investigated the effects of ethanol exposure during adolescence on the number of...

    Environmental neurotoxicants like benzo[a]pyrene (B[a]P) have been well documented regarding their potential to induce oxidative stress. However, neonatal exposure to B[a]P and its subsequent effect on anti-oxidant defence system and hippocampal cytomorphometry leading to behavioral changes have not been fully elucidated. We investigated the effect of acute exposure of B[a]P on five days old male Wistar pups administered with single dose of B[a]P (0.2 μg/kg BW) through intracisternal mode. Control group was administered with vehicle i.e., DMSO and a separate group of rats without any treatment was taken as naive group. Behavioral analysis showed anxiolytic-like behavior with significant increase in time spent in open arm in elevated plus maze. Further, significant reduction in fall off time during rotarod test showing B[a]P induced locomotor hyperactivity and impaired motor co-ordination in adolescent rats. B[a]P induced behavioral changes were further associated with altered anti-oxidant defence system involving significant reduction in the total ATPase, Na(+) K(+) ATPase, Mg(2+) ATPase, GR and GPx activity with a significant elevation in the activity of catalase and GST as compared to naive and control groups. Cytomorphometry of hippocampus showed that the number of neurons and glia in B[a]P treated group were significantly reduced as compared to naive and control. Subsequent observation showed that the area and perimeter of hippocampus, hippocampal neurons and neuronal nucleus were significantly reduced in B[a]P treated group as compared to naive and control. The findings of the present study suggest that the alteration in hippocampal cytomorphometry and neuronal population associated with impaired antioxidant signaling and mood in B[a]P treated group could be an outcome of neuromorphological alteration leading to pyknotic cell death or impaired differential migration of neurons during early postnatal brain development.

    Choice impulsivity has been linked to dopamine function and is consistently observed in attention deficit/hyperactivity disorder (ADHD) as a preference for smaller-immediate over larger-delayed rewards using choice-delay paradigms. More sophisticated delay discounting paradigms have yielded inconsistent results. Context and sample characteristics may have contributed to these variations. In this study we examine the effect of type (real vs hypothetical) and magnitude of reward as well as of variation in dopamine genes on choice impulsivity. We selected 36 male adolescents with ADHD-combined subtype (ADHD-CT) and 32 controls (mean age=15.42, SD=2.05) to form four roughly equally sized subgroups on the basis of DAT1(10/6) haplotype dosage (2 copies and <2 copies). Participants, who were also genotyped for the COMT(val158met) and DRD4(48bp-VNTR) polymorphisms, performed a hypothetical and a real-time discounting task and provided self-ratings of trait impulsivity. The ADHD-CT group discounted rewards more steeply than controls only in the hypothetical task, with delay, but not reward magnitude, influencing choices. They also rated themselves as more impulsive compared with controls. DAT1(10/6) dosage and the COMT(Val158Met) genotype predicted trait impulsivity and discounting rates in the hypothetical task, but not in the real-time task. Our results directly link variation in genes putatively influencing dopamine signaling in the prefrontal cortex (COMT(Val158Met)) and the striatum (DAT1(10/6)) with discounting rates in a hypothetical task (but not a real-time task) and self-ratings of trait impulsivity in ADHD-CT and healthy controls. The lack of magnitude effects in the hypothetical task suggests that discounting in this task may be influenced by different processes in ADHD-CT than in healthy controls. PMID:20736997

    Much research has examined Moffitt's developmental taxonomy, focusing almost exclusively on the distinction between life-course persistent and adolescence-limited offenders. Of interest, a handful of studies have identified a group of individuals whose early childhood years were marked by extensive antisocial behavior but who seemed to recover and desist (at least from severe offending) in adolescence and early adulthood. We use data from the Cambridge Study in Delinquent Development to examine the adult adjustment outcomes of different groups of offenders, including a recoveries group, in late middle adulthood, offering the most comprehensive investigation of this particular group to date. Findings indicate that abstainers comprise the largest group of males followed by adolescence-limited offenders, recoveries, and life-course persistent offenders. Furthermore, the results reveal that a host of adult adjustment problems measured at ages 32 and 48 in a number of life-course domains are differentially distributed across these four offender groups. In addition, the recoveries and life-course persistent offenders often show the greatest number of adult adjustment problems relative to the adolescence-limited offenders and abstainers.

O início da vida sexual ocorreu, entre outros, por conta da atração física, da curiosidade e do desejo de perder a virgindade, sugerindo um caráter mais próximo do papel social masculino. Por outro lado, a maior parte dos adolescentes virgens justificou sua opção por questões de ordem romântica, como não ter encontrado a pessoa certa ou porque gostaria de casar-se virgem. Os resultados revelaram um duplo padrão social em que há a valorização do sentimento de amor e entrega à pessoa amada simultaneamente à premência física e instintiva para o sexo. Padrões tradicionais de masculinidade, como a dissociação entre sexo e amor, parecem estar sendo transpostos no tocante à iniciação sexual, revelando diversidade nos modos de viver a sexualidade na adolescência que, por sua vez, estão relacionados à saúde sexual e reprodutiva dos homens e suas parcerias.This article describes male adolescents' affective history and reasons for initiating or postponing sexual activity, using interviews with 184 males ages 15 to 19 and residing in the city of São Paulo, Brazil, in 2002. Factors for sexual debut included physical attraction, curiosity, and the desire to lose their virginity, suggesting a profile similar to the male social role. Most of the virgin adolescent males justified their choice based on issues of a romantic order, such as not having found the right person or because they preferred to remain virgin until marrying. The results showed a dual social pattern, valuing the feeling of love and deliverance to the loved one, simultaneously with the pressing physical and instinctive desire for sex.

    Substantial increases in pediatric and adult obesity in the US have prompted a major revision to the current UF/NCI (University of Florida/National Cancer Institute) family of hybrid computational phantoms to more accurately reflect current trends in larger body morphometry. A decision was made to construct the new library in a gridded fashion by height/weight without further reference to age-dependent weight/height percentiles as these become quickly outdated. At each height/weight combination, circumferential parameters were defined and used for phantom construction. All morphometric data for the new library were taken from the CDC NHANES survey data over the time period 1999-2006, the most recent reported survey period. A subset of the phantom library was then used in a CT organ dose sensitivity study to examine the degree to which body morphometry influences the magnitude of organ doses for patients that are underweight to morbidly obese in body size. Using primary and secondary morphometric parameters, grids containing 100 adult male height/weight bins, 93 adult female height/weight bins, 85 pediatric male height/weight bins and 73 pediatric female height/weight bins were constructed. These grids served as the blueprints for construction of a comprehensive library of patient-dependent phantoms containing 351 computational phantoms. At a given phantom standing height, normalized CT organ doses were shown to linearly decrease with increasing phantom BMI for pediatric males, while curvilinear decreases in organ dose were shown with increasing phantom BMI for adult females. These results suggest that one very useful application of the phantom library would be the construction of a pre-computed dose library for CT imaging as needed for patient dose-tracking.

    Full Text Available A discriminação e a violência contra o gênero feminino associam-se a representações distorcidas da mulher. Este trabalho tem o objetivo de mensurar a existência de preconceitos nas manifestações dos estereótipos de gênero e sexismo ambivalente, em adolescentes masculinos de 12 a 16 anos. Em um estudo transversal, aplicaram-se três questionários (sociodemográfico, Gender stereotyping, Inventário do Sexismo Ambivalente a 787 estudantes de 11 escolas públicas. Nos resultados, detectou-se a presença de estereótipos de gênero. Houve diferença significante entre alunos de escolas estaduais e municipais e também nos alunos que estudavam em bairros de poder aquisitivo elevado em relação aos demais. O sexismo, também presente, apresentou-se significantemente mais benévolo que hostil. O escore para o componente benévolo variou conforme a escola cursada. O hostil não foi influenciado pelas variáveis estudadas. Os achados corroboram a existência de estereótipos de gênero e sexismo ambivalente nos adolescentes masculinos e a necessidade de desenvolvimento de ações e políticas para sua erradicação.Discrimination and violence against the female gender are associated with distorted representation of women.

    Full Text Available Introduction Numerous studies have shown that sexual behavior increases among adolescents. Disharmony between biological and psychosocial maturity among young people may cause risky behavior, and endanger psychophysical and reproductive health of young persons. Material and methods A questionnaire on sexual behavior was completed by 169 adolescents, 1st and 4th year high school students. Results Every 6th first grade and every 2nd forth grade adolescent is sexually active. Male adolescents begin sexual activities significantly earlier (at the age of 15.6 than female adolescents (16.5. Also, young men have significantly more partners (3.6 than girls (1.3, and more parallel sexual relations than girls. Only 1/3 of sexually active adolescents always use some kind of contraception, more frequently boys (41.9% than girls (26.7%. Discussion Early commencement of sexual activity results with longer active period before realization of the reproductive function, which increases risk for reproductive health disorders. Unprotected sexual intercourse and large number of partners also present significant risk factors. Conclusion Sexual life of adolescents begins at the age of 16, on average, and only every third always uses contraceptive protection, which points to a need for better education on reproductive health by using contemporary methods. It is also necessary to increase availability of contraceptives (condoms at all places where adolescents spend time (in schools, bars, cinemas, disco clubs etc. in order to achieve responsible sexual behavior and protection of reproductive health among youth.

    Full Text Available Abstract Background Sexual activities are increasingly changing from the cultural point of view what they used to be. Knowledge of these practices among adolescents may be a basis to create awareness among adolescents on practices that involve risks. This study aims to assess sexual practices among unmarried adolescents in Tanzania. Methods A cross-sectional survey was conducted among in-school and out-of-school but unmarried adolescents aged 10 to 19 in five locations in Tanzania. A questionnaire was used to collect information and to characterize sexual practices among these adolescents. Results About 32% of adolescents reported being sexually active; a higher proportion being males than females. The only inquired and reported sexual practices include vaginal sex, masturbation, oral and anal sex. About 15% of sexually active adolescents reported having multiple sexual partners. Significantly more males reported having multiple partners than females. Nearly 42% of sexually active adolescents reported having used a condom during most recent sexual act. Females reported older partners at first sexual act. Conclusion Adolescents experience several sexual practices that include penetrative and non-penetrative. More males reported being sexually active than females. Despite adolescents reporting having multiple sexual partners, reported condom use during the most recent sexual act was low. We advocate for a more enhanced approach of reproductive health education that includes safer sex to adolescents without forgetting those in-schools.

    2015-01-01

    Prior evidence suggested thatMAOA gene was an potentially important candidate gene of depression, and its association with depression was mediated by environmental factors. However, most of the studies in this area have been guided by the "diathesis and stress model" and have typically focused on the interaction between MAOA gene and adverse environments, such as child maltreatment and stressful life events. Peer relationship, including peer accept and peer rejection, is among the important interpersonal relationships during early adolescence and plays a critical role in adolescent psychosocial development. However, it still remains unclear whether and how peer relationships interact withMAOA gene on adolescent depression. Additionally, previous studies examined mainly the effects ofMAOA-uVNTR polymorphism on depression, and rarely focused on rs6323 polymorphism, which has been identified as a common polymorphism site among Asians. This study aimed to examine the interaction between rs6323 polymorphism and peer acceptance/rejection on early adolescent depression, with the differential susceptibility model as the theoretical frame. The participants in this study included 683 male adolescents originally drawn from a 3-year longitudinal study (n=1323) which investigated 11 junior high schools obtained through a random cluster sampling method. During the initial assessment (in 2010), adolescents (grade 7) were on average 13.53 years old (SD=0.51). Adolescents' depression were measured using self-rated Children's Depression Inventory (2010:α = 0.87; 2012:α = 0.88), while peer relationship (including peer acceptance and peer rejection) were rated by peer nomination. DNA was extracted from saliva. Genotype at rs6323 was performed in real time with MassARRAY RT software version 3.0.0.4 and analyzed using the MassARRAY Typer software version 3.4 (Sequenom).

    Full Text Available Osteoporosis in men is now recognized as an increasingly important public health issue. About 30 % of hip fractures and 20 % of vertebral fractures occur in men. In the present study, we examined 19 men who did not have major risk factors that might affect bone mass. Parathormone(PTH, osteocalcin (marker of bone formation, OC and deoxypyridinoline (marker of bone resorption, DPD were measured. The bone mineral density (BMD measurements in 16 men were performed by dual-energy X-ray absorbtiometry (DXA from lumbar spine (L2-4, and left hip. Bone density at each site was categorized as osteoporosis or osteopenia according to World Health Organization (WHO criteria. In 19 patients with a mean age of 69 years, PTH levels were in the normal range except one patient. OC levels were elevated in %42.1 and DPD levels were elevated in 74 % of patients. L2-4 T score was osteoporotic (25% in 4 patients and osteopenic (25% in 4 patients. Femur Ward’s T score was osteoporotic (37.5% in 7 patients and osteopenic (37.5% in 7 patients. Osteoporosis is a significant problem in older men. Increased awareness for the risk factors of male osteoporosis is an important issue. Early diagnosis and treatment would help to reduce morbidity and mortality resulting from osteoporotic fractures.

    2013-09-01

    Do adolescents model their mothers' self-objectification? We measured self-objectification (body surveillance and body shame), body mass index (BMI), body esteem, and quality of the mother-adolescent relationship in 179 female and 162 male adolescents at age 15, as well as self-objectification in their mothers. Initial analyses indicated no improvement in model fit if paths were allowed to differ for females and males; therefore a single model was tested for the combined sample. Findings revealed that mothers' body surveillance negatively predicted adolescents' body surveillance. Mothers' body shame was unrelated to adolescents' body shame, but positively predicted adolescents' body surveillance. Results for the relationship between mothers' and adolescents' self-objectification suggest that adolescents engaged in more individuation than modeling. A more positive mother-adolescent relationship predicted lower body shame and higher body esteem in adolescents, suggesting that the quality of the relationship with the mother may be a protective factor for adolescents' body image. Mother-adolescent relationship quality did not moderate the association between mothers' and adolescents' self-objectification. These findings contribute to our understanding about the sociocultural role of parents in adolescents' body image and inform interventions addressing negative body image in this age group. The quality of the mother-adolescent relationship is a clear point of entry for such interventions. Therapists should work with adolescents and their mothers toward a more positive relationship quality, which could then positively impact adolescents' body image. PMID:24363490

    Memisevic, Haris; Mujkanovic, Edin; Ibralic-Biscevic, Inga

    2016-08-01

    Emotion recognition is very important for successful social interactions. This study compared adolescents with intellectual disability and adolescents with hearing impairment on a facial emotion recognition task. The sample for this study comprised 78 adolescents (46.2% females, 53.8% males; M age = 16.4, SD = 1.0) divided into three groups (N = 26) of adolescents with intellectual disability, adolescents with hearing impairment, and adolescents without disabilities. Emotion recognition abilities were measured using a computerized Emotion Recognition Test. Adolescents with intellectual disability achieved lower scores on Emotion Recognition Test in comparison with adolescents with hearing impairment and adolescents without disabilities. There were no significant differences on Emotion Recognition Test between adolescents with hearing impairment and adolescents without disabilities. Given the importance of emotion recognition in everyday functioning, it is of crucial importance to have emotional training programs as part of the school curriculum. PMID:27440764

    153 sexually active 11th and 12th graders attending two inner-city high schools in San Francisco participated in a study of strategies adolescents use to secure sexual intercourse with a partner. The study sample comprised 20 male and 16 female African-Americans, 21 male and 22 female Caucasians, 17 male and 18 female Chinese-Americans, and 19 male and 20 female Mexican-Americans aged 14-19 years (mean age, 16.96 years). Non-English-speaking and special education students were excluded from study. Relative to females, males reported using a higher degree of pressure, rape, lying, and getting a partner drunk or high to encourage sexual involvement. Both sexes reported suggesting interest in developing commitment and a relationship with the intended sex partner to achieve the goal of intercourse. Females mentioned more strategies than males which signaled sexual availability. Relative to adults, the study participants reported fewer strategies and were less focused upon appearance enhancement and the intricacies of dating. PMID:9098732

  6. Adolescents and human immunodeficiency virus infection.

    Science.gov (United States)

    Anderson, J R

    1992-12-01

    As of March 31, 1992, individuals 13 to 19 years of age had been diagnosed with acquired immunodeficiency syndrome; over one third were diagnosed in the past 2 years alone. Because of the long incubation period from initial infection to acquired immunodeficiency syndrome diagnosis, the majority of young adults with acquired immunodeficiency syndrome were probably initially infected as adolescents. In 1991, 34% of adolescents with acquired immunodeficiency syndrome were female, and their predominant mode of transmission was heterosexual contact. Human immunodeficiency virus seroprevalence studies of adolescents show a male-to-female ratio approaching 1:1, with many human immunodeficiency virus-infected adolescent women identifying none of the standard risk. Factors such as sexual and drug experimentation, risk taking, and sense of invulnerability so characteristic of adolescence put adolescents at special risk for human immunodeficiency virus. There is no published information on if or how clinical manifestations of human immunodeficiency virus disease in adolescents might differ from those seen in adults. Medical care should be broad-based and should include access to clinical trials for new drug treatments. General knowledge levels about acquired immunodeficiency syndrome are high among US adolescents, but behavioral changes have lagged behind. All adolescents should be targeted for intensive education about human immunodeficiency virus along with interventions designed to enhance their general coping, communication, and decision-making skills.

  8. Interpersonal factors associated with depression in adolescents: are these consistent with theories underpinning interpersonal psychotherapy?

    Science.gov (United States)

    O'Shea, Gabrielle; Spence, Susan H; Donovan, Caroline L

    2014-01-01

    The aim of this study was to investigate whether depressed adolescents differed from non-depressed adolescents in terms of constructs consistent with those that are proposed to underpin interpersonal psychotherapy. In particular, it was hypothesized that compared with non-depressed adolescents, depressed adolescents would demonstrate a greater number of negative life events associated with interpersonal loss and major life transitions, a more insecure attachment style and poorer communication skills, interpersonal relationships and social support. Thirty-one clinically diagnosed depressed adolescents were matched with 31 non-depressed adolescents on age, gender and socio-economic status. The 62 participants were aged between 12 and 19 years and comprised 18 male and 44 female adolescents. On a self-report questionnaire, depressed adolescents reported a greater number of negative interpersonal life events, a less secure attachment style and scored higher on all insecure attachment styles compared with the non-depressed adolescents. In addition, depressed adolescents demonstrated lower levels of social skill (on both adolescent and parent report), a poorer quality of relationship with parents (on both adolescent and parent report) and lower social competence (adolescent report only). Parents of depressed adolescents also reported more negative parental attitudes and behaviours towards their adolescent compared with parents of non-depressed adolescents. Thus, the results of this study are consistent with the constructs underlying interpersonal psychotherapy and suggest their usefulness in the assessment, conceptualization and treatment of adolescent depression. Clinical implications are discussed. PMID:23801523

    Duggal, S; Carlson, E A; Sroufe, L A; Egeland, B

    2001-01-01

    Antecedents of depressive symptomatology in childhood and adolescence were examined in a prospective longitudinal study of at-risk youth (n = 168) from families of lower socioeconomic status. Relations between family context factors, maternal depressive symptoms, and depressive symptoms in childhood and adolescence were examined, with a focus on early family relationship factors rarely available for analysis in longitudinal data sets. Results suggest the possibility of etiological differences between depressive symptoms in childhood and in adolescence. Depressive symptomatology in childhood was predicted by the overall family context. Cumulative effects of maternal depressive symptomatology, early care lacking in emotional supportiveness, abuse, and family stressors were observed. Depressive symptomatology in adolescence, on the other hand, was specifically associated with maternal depression and early care lacking in emotional supportiveness. Moreover, an intriguing sex difference emerged: maternal depressive symptomatology was strongly associated with depressive symptomatology in adolescence for females, but for males supportive early care appeared more relevant.

  7. Psychosexual issues in adolescent contraception.

    Science.gov (United States)

    Greer, J G

    1982-01-01

    This paper reviews the psychosocial and developmental research focusing on adolescent contraception. Specific emphasis is on the interrelationship of psychosexual development and culture in preventing or exacerbating problems. Attention is directed to the following: program policy and planning; major literature reviews on adolescent sexuality; female development and early coitus; the male partner; the competent adolescent contraceptor; and directions for future research (psychological sequelae of early coitus in girls, factors affecting delay of 1st coitus in girls, and the promotion of competent contraceptive behavior). In the less developed countries, efforts to delay 1st birth and increase birth spacing must form part of the overall strategy to upgrade the survival rates and health of infants. Ancillary to such urgent public health policy concerns is the current worldwide spread of the modern feminist social movement, generating pressures to make education and work opportunities available to female adolescents in the 3rd world. Adolescent pregnancy in the developed countries is not a major world health problem; prenatal care and adequate nutrition are feasible for the pregnant teenager. Yet, no cultural supports exist for such mother-infant dyads, and such pregnancies are viewed, particularly by educated women, as reversing a developed nation's social progress. There has been a growing effort in the US to implement contraceptive programs directed at the sexually active female adolescent between menarche and age 18. Issues other than availability of abortion and contraceptive supplies are also operating. Developmental level of the public health service user and specifically psychosexual developmental level, is a factor which must be considered in program policy and planning. Developmentally, the logical course of introduction to sexuality for young females would be solitary masturbation, heterosexual mutual masturbation, and coitus. Cultures at ease with

    The purpose of this study was to examine maternal and adolescent depression, maternal and teen sensation seeking, and maternal smoking, and their associations with adolescent smoking. Data were collected from a sample of 47 male and 66 female adolescents (ages 11—18 years) and their mothers from three different health clinics. The findings indicated that maternal sensation seeking was linked indirectly with adolescent smoking through teen sensation seeking, both of which were significantly as...

    Ethanol has been reported to disrupt spatial learning and memory in adolescent male rats. The present study was undertaken to determine the effects of ethanol on the acquisition of spatial memory in adolescent female rats. Adolescent female rats were subjected to repeated ethanol or saline treatments, and spatial learning was tested in the Morris water maze. For comparison, adult female rats were subjected to similar ethanol treatment and behavioral assessments as for adolescent rats. Ethanol...

    Full Text Available This paper utilizes existing statistics on adolescent suicide to examine adolescent suicide trends and patterns in Hong Kong for the period 1980 to 2003. Several trends and patterns could be revealed from the analyses. First, there was a gradual rising trend where adolescent suicide rates in the 1990's and the early 2000's were higher than those in the 1980's. Second, suicide rates for adolescents aged 10-24 years were lower than those of other adult age groups. Third, although adolescent suicide rates in Hong Kong were lower than those reported in some English-speaking countries and Mainland China, the figures were higher than those reported in Taiwan. Fourth, suicide rates among teenagers in early adolescence were lower than those among adolescents in late adolescence. Fifth, although male adolescent suicide rates were in general higher than female adolescent suicide rates (10-24 age group, gender differences in suicide rates appeared to be moderated by age. Sixth, there was a gradual rising trend in adolescent proportional mortality rates for suicide since the 1990's. Seventh, proportional mortality rates for suicide among teenagers in early adolescence were lower than those among adolescents in late adolescence. Finally, although jumping from a height was a common method of adolescent suicide, there was a rising trend of using other methods, such as taking drugs, hanging and charcoal burning. The observed adolescent suicide phenomena are discussed in this study with reference to the socio-cultural context of Hong Kong.

  15. Adolescent pregnancy.

    1994-01-01

    Kentucky has the fourth highest percentage of infants born to teenage mothers in the US. Risk factors for adolescent pregnancy are poor academic performance, family history of adolescent pregnancy, absence of one or both biological parents in the home, troubled family relationships, family violence, history of substance abuse, and poor self-concept. Pregnancy adds new developmental requirements to the continual developmental crisis of adolescence. Some of these developmental requirements are dealing with pregnancy and birth of a child and peer and family reactions and relationships. Pregnant teens are at high risk for anemia, preeclampsia, preterm delivery, and low birth weight infants. The health care team must assess the abilities, needs, practices, and priorities of teens. Nurses should promote health and positive health practices in teens. They should focus on prevention of adolescent pregnancy and on meeting the needs of pregnant teens. Adolescent pregnancy interventions include education and adolescent-centered special programs. Peer groups, role playing, videos, and computer games are individualized and effective education techniques for teens. Formal adolescent pregnancy prevention programs are abstinence education, knowledge-based programs, and clinic-focused or school-based programs. A combination of approaches is more effective than using just one approach. Adolescent pregnancy prevention interventions should promote the value of education, discourage substance abuse, and provide counseling for victims of child abuse. Pregnant teens should receive prenatal care as soon as possible. One health care agency should combine physical care, psychosocial support, and education for teens. Kentucky schools help pregnant teens continue their education and help them obtain information and support for care for themselves and their babies. Nurses can be effective at reducing the number of unwanted teen pregnancies. PMID:7934083

    2010-03-01

    Adolescence, between the ages of 10 and 19 years, is a unique period both physically and emotionally. During this time of life, individuals are known to experiment and engage in risky behavior, sometimes with unforeseen morbidity and mortality. We also see suicide emerge as a manner of death in this age group. The most common method is gunshot wound and sometimes in the form of Russian roulette. Few studies have looked at deaths by Russian roulette, the victims, and scenarios. In particular, no study examines the adolescent victim of Russian roulette. To better understand and classify this entity, adolescent Russian roulette autopsy cases over a 20-year period were examined looking at the victims, scenarios, autopsy findings, cause and manner of death, and the weapons. All victims were males, ages 13 to 19 years, with a Black-to-White ratio of 1:1. No victim had a previous psychiatric history. Toxicology was positive for alcohol and/or marijuana in 50% of the victims. Friends were present when the victim shot himself which occurred in the home the majority of the time. In all but 1 case, premeditation of the game was involved as the victim provided the weapon for the roulette. The cause of death was gunshot wound to the head (6 to the right side, 1 to the mouth, 1 to the forehead), and the manner of death was suicide in 6 cases and accident in 2 cases. A review of the literature discusses the adolescent victim, suicide, and Russian roulette. PMID:20010290

    2016-06-01

    The present study concerned adolescents' needs for social support with a focus on specific situations. The Adolescent Need for Social Support Questionnaire (ANSSQ) was developed based on qualitative interviews with typically developing adolescents about situations in which they need parent support. The questionnaire was tested on a sample of 380 Swedish 15-year-olds. A 3-component structure reflecting the dimensions "Home and school", "Low mood", and "Sex and alcohol" was tested in SEM analyses. Scales based on these dimensions, measuring support from parents and peers, yielded satisfactory psychometric results. Parent support was preferred over peer support for "Home and school" situations; in the other two areas peers were more likely to be the support providers. Females turned more often to parents and friends for support than males. Seeking parental support was positively related to adolescent disclosure and negatively related to adolescent secrecy, indicating convergent and discriminant validity. Further validation of the ANSSQ is discussed. The current study points to possibilities for adapting measures of social support to contexts. PMID:27038341

Foram realizados quatro grupos focais com 34 estudantes adolescentes da rede de ensino público e privado, contrastando gênero e origem social. A análise intra e intergrupal do material discursivo fundamentou-se num enfoque crítico-interpretativo. Dentre os temas identificados, abordamos "as relações de gênero", estruturando a exposição em torno de três dimensões: a confiança, a submissão e a iniciativa, que emergiram como eixos centrais. Os achados deste estudo ressaltam que a tão propalada desigualdade de poder entre os gêneros não se evidencia na fala dos adolescentes, ganhando, ao contrário, uma aparência de eqüidade na negociação e na falta de iniciativa para o uso do preservativo. São sutis as diferenças encontradas entre as escolas públicas e privadas. Mudanças podem estar ocorrendo neste campo do comportamento sexual entre adolescentes, o que ressalta a importância dos canais de diálogo, considerando-se a singularidade dos grupos na construção de estratégias adequadas aos atores sociais em seus contextos históricos e culturais.This study assessed gender-related aspects involved in the inconsistent use of male condoms by adolescents in Rio de Janeiro, Brazil.

    1994-05-01

    Adolescence is a phase of human development which is marked by a high vulnerability due to the ongoing psycho-physiological transformations. The regulation of the self-esteem is especially in danger in youngsters who went into adolescence with a marked burden of conflicts or who lived in families with disturbed intrafamilial dynamics. To be present as a partner and not to find the solutions for the adolescents' conflicts, to accept their questioning of what is established and to recognize their movements of reconciliation are the quite complex demands put on to the world of the adults. Adolescents urge us to a review of our own adolescence, to a balancing of hate and love, openness and rigidity, and to dialectic movements between disintegration and reintegration as well as between the generations. Any help, be it on the physical, the social or the psychic level, should be directed toward a restitution of the intrapsychic, intrafamilial or intergenerational balance; sociocultural factors have also always to be respected. The helpers--especially in a culture with rapid change--are often confronted with their own adolescence, which took place a generation before and mostly under totally different conditions.

    Media are one source for adolescent identity development and social identity gratifications. Nielsen viewing data across the 2014-2015 television season for adolescents ages 14-17 was used to examine racial and gender diversity in adolescent television exposure. Compared to US Census data, mainstream shows under represent women, but the proportion of Black characters is roughly representative. Black adolescents watch more television than non-Black adolescents and, after taking this into account, shows popular with Black adolescents are more likely than shows popular with non-Black adolescents to exhibit racial diversity. In addition, shows popular with female adolescents are more likely than shows popular with males to exhibit gender diversity. These results support the idea that adolescents seek out media messages with characters that are members of their identity groups, possibly because the characters serve as tools for identity development and social identity gratifications.

    Full Text Available Abstract Background Suicide is the leading cause of death among Japanese adolescents, and they may commit suicide differently from adults. However, there are few studies in medical-based data concerning adolescent patients seriously attempting suicide. We aimed to explore the characteristics of serious suicide attempts in Japanese adolescents, comparing them with those in adults. Methods We investigated adolescents who seriously attempted suicide and were treated at the Critical Care Medical Center (CCMC of Nippon Medical School Hospital between 2000 and 2010, and we compared them with adult suicide attempters treated during 2009. We retrospectively studied medical records and collected clinical data and socio-demographic factors, including age, sex, psychiatric symptoms or diagnosis, methods of suicide attempt, motives for suicide attempt, previous deliberate self-harm, previous psychiatric history, parent loss experience, and previous psychiatric history in the family. Results Adolescent attempters were 15 males and 44 females, 13 to 18 years old (mean 16.39. Adult attempters were 37 males and 65 females, 19 to 79 years old (mean 39.45. In comparison to adult attempters, adolescent attempters were more frequently diagnosed with Borderline Personality Disorder (BPD, had more school problems and parent loss experience, but they had less financial problems. Gender differences between adolescents and adults were examined, and male adolescent attempters were found to be more frequently diagnosed with schizophrenia and had less financial problems than their adult counterparts, while female adolescent attempters were more frequently diagnosed with BPD, had more school problems and parent loss, but they had less previous psychiatric history than their adult counterparts. Conclusions Our findings indicated that adolescent attempters were more frequently diagnosed with BPD and had more school problems and parent loss experience but had less financial

  5. Inhibiting influence of testosterone on stress responsiveness during adolescence.

    The maturation of the hypothalamo-pituitary-adrenal (HPA) axis is a key-component of the changes that occur during adolescence. In guinea pigs, HPA responsiveness during late adolescence depends strongly on the quantity and quality of social interactions: Males that lived in a large mixed-sex colony over the course of adolescence exhibit a lower stress response than males that were kept in pairs (one male/one female). Since colony-housed males have higher testosterone (T) levels than pair-housed males, and inhibiting effects of T on HPA function are well known, we tested the hypothesis that the decrease in stress responsiveness found in colony-housed males is due to their high T concentrations. We manipulated T levels in two experiments: 1) gonadectomy/sham-gonadectomy of colony-housed males (which usually have high T levels), 2) application of T undecanoate/vehicle to pair-housed males (which usually have low T levels). As expected, gonadectomized males showed a significantly increased stress response in comparison with sham-gonadectomized males, and T-injected males had a significantly lower stress response than vehicle-injected males. Both experiments thus confirm an inhibiting effect of T on HPA responsiveness during adolescence, which can mediate the influence of social interactions. The reduction in stress responsiveness is hypothesized to have a biologically adaptive value: A sudden increase in glucocorticoid concentrations can enhance aggressive behavior. Thus, pair-housed males might be adapted to aggressively defend their female ('resource defense strategy'), whereas colony-housed males display little aggressive behavior and are capable of integrating themselves into a colony ('queuing strategy').

    The nuclear receptor Tlx is a key regulator of embryonic and adult hippocampal neurogenesis and has been genetically linked to bipolar disorder. Mice lacking Tlx (Nr2e1(-/-)) display deficits in adult hippocampal neurogenesis and behavioural abnormalities. However, whether Tlx regulates behaviour during adolescence or in a sex-dependent manner remains unexplored. Therefore, we investigated the role of Tlx in a series of behavioural tasks in adolescent male and female mice with a spontaneous deletion of Tlx (Nr2e1(-/-) mice). Testing commenced at adolescence (postnatal day 28) and continued until adulthood (postnatal day 67). Adolescent male and female Nr2e1(-/-) mice were hyperactive in an open field, an effect that persisted in adulthood. Male but not female Nr2e1(-/-) mice exhibited reduced thigmotaxis during adolescence and adulthood. Impairments in rotarod motor performance developed in male and female Nr2e1(-/-) mice at the onset of adulthood. Spontaneous alternation in the Y-maze, a hippocampus-dependent task, was impaired in adolescent but not adult male and female Nr2e1(-/-) mice. Contextual fear conditioning was impaired in adolescent male Nr2e1(-/-) mice only, but both male and female adolescent Nr2e1(-/-) mice showed impaired cued fear conditioning, a hippocampal-amygdala dependent cognitive process. These deficits persisted into adulthood in males but not females. In conclusion, deletion of Tlx impairs motor, cognitive and anxiety-related behaviours during adolescence and adulthood in male and female mice with most effects occurring during adolescence rather than adulthood, independent of housing conditions. This suggests that Tlx has functions beyond regulation of adult hippocampal neurogenesis, and may be an important target in understanding neurobiological disorders. PMID:26970576

    Objective To explore the empathy deficits of adolescents with different types of conduct disorder. Methods The participants included 65 adolescents ( who met the DSM-Ⅳ criteria for conduct disorder)ranging from 13 ~ 18 in age,and 195 normal adolescents ranging from 13 ~ 18 in age. All participants were assessed by revised Basic Empathy Scale. 65 patients were divided into 4 subgroups according to symptoms: destructive-nondestructive subgroups and overt-covert subgroups. Results (1) Scores of cognitive empathy were lower in patients than normal controls ( (29.86 ± 4.72) vs ( 32.09 ± 4.94), P < 0. 01 ). (2) There were significant differences in the levels of cognitive empathy between patients and controls (P<0. 01 ). Scores of cognitive empathy were lower in destructive subgroup than controls ( (29.76 ± 4.46) vs ( 32.09 ± 4.94) , P < 0.01 ). (3) There were significant differences in the levels of two dimensions and total scores of empathy between patients and controls (F=3.10 ~5.36, P < 0.05 ). Scores of cognitive empathy were lower in overt subgroup ( 29.22 ± 3.77 ) and covert subgroup (30.21 ± 5.17 ) than controls (32.09 ± 4.94) (P< 0.05, P<0.01 );and scores of affective empathy were lower in overt subgroup than covert subgroup ( (26.13 ±5.05) vs (29.50 ±4.16), P<0.05 ). Total scores of empathy were lower in overt subgroup (55.35 ±7.09) than covert subgroup (59.71 ±7.58) and controls (60.04 ±8.50 ) (P<0.05). (4) Logistic regression analysis showed that cognitive empathy was a protective factor for conduct disorders( OR = 0.43 ). Conclusion The cognitive empathy level of patients is significantly lower than normal students;and boys with different types of conduct disorder possess different empathic abilities when compared with healthy controls;and cognitive empathy is a protective factor for conduct disorder.%目的 探讨不同类型男性品行障碍青少年的移情缺陷.方法 采用基本移情量表中文版对65名男性

    2011-09-01

    Full Text Available Adolescence is the core stage for the development of the value system, one of the most important determinants of the human identity. The issue discussed in this paper is the perception of the value system by the people with impaired hearing who constitute a cultural minority. Such assumption can be made based on the cross-cultural value survey conducted by S.H. Schwartz. The Schwartz’s approach was chosen in this research to measure the culture on individual level.Sixty-six deaf adolescent students from secondary residential schools aged between15 and 20 years (29 male, 37 female and 93 hearing students from boarding middle schools aged between 15 and 17 years (39 male and 54 female were tested by using the Schwartz Portrait Values Questionnaire.The results showed that the intergroup value system differences were modified by gender. Hearing adolescent males considered bene­volence, hedonism and stimulation as more important than female adolescents did. In the deaf subgroup, the females valued security, power and achievement more than males. The mode of communication within the family had only one significant effect: the use of signing language implies significantly higher level of conformity in comparison to the people who communicate verbally.

    The goal of this study was to compare the processing of social information in deaf and hearing adolescents. A task was developed to assess social information processing (SIP) skills of deaf adolescents based on Crick and Dodge's (1994; A review and reformulation of social information-processing mechanisms in children's social adjustment. Psychological Bulletin, 115, 74-101) reformulated six-stage model. It consisted of a structured interview after watching 18 scenes of situations depicting participation in a peer group or provocations by peers. Participants included 32 deaf and 20 hearing adolescents and young adults aged between 13 and 21 years. Deaf adolescents and adults had lower scores than hearing participants in all the steps of the SIP model (coding, interpretation, goal formulation, response generation, response decision, and representation). However, deaf girls and women had better scores on social adjustment and on some SIP skills than deaf male participants. PMID:27143715

    Full Text Available Abstract Background Prevalence of tobacco use among adolescents in India is very high. Despite many epidemiological studies exploring tobacco use among youth, there is no published data on adolescents' perceptions about smokers in Indian society and its implications on tobacco control. Methods A cross-sectional study was conducted using a stratified random sampling with probability proportional to school-type (government or private owned. Data was collected using a pretested, self-administered, anonymous questionnaire with a mix of close and open-ended questions from a sample of 1087 students. Chi-square test was used to measure associations. Qualitative data was analysed through inductive coding. Results The response rate for the study was 82.5% and the sample population had a mean age of 16.9 years (SD = 1.9 with 57.8% male students. Majority of respondents (84.6% reported negative perceptions about smokers while 20.4% of respondents reported positive perceptions. Female students reported significantly higher disapproval rate (negative perceptions for smoking compared to male students (89.7% Vs 71.6% in case of male smoker; 81.2% Vs 67.3% in case of female smoker. Dominant themes defining perceptions about smokers included 'hatred/hostility/Intolerance', 'against family values/norms', 'not aware of tobacco harms' and 'under stress/emotional trauma'. Themes like 'culture', 'character' and 'power' specifically described negative social image of female smoker but projected a neutral or sometimes even a positive image of male smoker. There was a significant association between adolescents' positive perceptions of smokers and tobacco use by themselves as well as their close associates. Conclusions Adolescents' stereotypes of smokers, especially female smokers are largely negative. We suggest that tobacco control interventions targeting adolescents should be gender specific, should also involve their peers, family and school personnel, and should go

    Deletions of the 15q26 region encompassing the chromodomain helicase DNA binding domain 2 (CHD2) gene have been associated with intellectual disability, behavioral problems, and several types of epilepsy. Including the cases mentioned in ECARUCA (European cytogeneticists association register of unbalanced chromosome aberrations) and DECIPHER (database of genomic variation and phenotype in humans using ensembl resources), so far, a total of 13 intellectually disabled patients with a genetically proven deletion of the CHD2 gene are described, of whom eleven had a history of severe forms of epilepsy starting from a young age. In this article, a moderately intellectually disabled 15-year-old male with a 15q26.1–q26.2 interstitial deletion is reported, who was referred for analysis of two recent short-lasting psychotic episodes that were nonresponsive to antipsychotic treatment and recurrent disinhibited behaviors since early infancy. Careful interdisciplinary assessment revealed that the psychotic phenomena originated from a previously unrecognized absence epilepsy. Treatment with valproic acid was started which resulted in full remission of psychotic symptoms, and consequently, substantial improvement of behavior. It was concluded that in case of (rare) developmental disorders with genetically proven etiology, a detailed inventory of anamnestic data and description of symptomatology over time may elucidate epilepsy-related psychopathology for which a specific treatment regimen is needed.

    A number of studies have indicated that monosodium glutamate (MSG) might cause negative effects on the nervous system, including in the cerebellum. Garlic (Allium sativum) has long been known as a flavouring agent and a traditional remedy for various illnesses. The present study aimed at investigating the effects of garlic on the motor coordination and the number of Purkinje cells present in rats treated with MSG. A total of 25 male Wistar rats aged 4 to 5 weeks old were used in this study and were divided into five groups, namely a negative control (C-) group, which received 0.9 % NaCl solution, a positive control (C+) group, which received MSG, and three treated groups, which received 2 mg/g bw of MSG and 2.5 mg (T2.5), 5 mg (T5), or 10 mg (T10) of black garlic solution per oral administration (per 200 g bw), respectively. All treatments were carried out for 10 days. Upon the end of the treatment, the motor performance of all rats were tested using the rotarod apparatus. The rats were subsequently sacrificed, and the cerebella of the rats were processed for stereological analyses. It has been found that the number of Purkinje cells of the cerebella of all treated groups were significantly higher than that of the group treated with MSG only. No changes in motor coordination function were observed as a result of MSG treatment. PMID:24737450

    Full Text Available Clinical diagnoses of Attention Deficit Hyperactivity Disorder (ADHD and the use of prescription medications for its treatment have increased in recent years. Current treatments may involve the administration of amphetamine-type substances, a treatment path many parents are apprehensive to take. Therefore, alternative pharmacological treatments are required. Few nutritional or pharmacological alternatives that reduce ADHD associated symptoms (hyperactivity and inattention have been subjected to rigorous clinical trials. Bacopa monnieri is a perennial creeping herb. CDRI 08 is a special extract of Bacopa monnieri which has been subjected to hundreds of scientific studies and has been shown in human randomized controlled trials (RCTs to improve memory, attention, and mood. It is hypothesised that chronic administration of CDRI 08 will improve attention, concentration and behaviour in children with high levels of hyperactivity and/or inattention. This paper reports the protocol for the first 16-week, randomized, placebo-controlled, double-blind, parallel groups trial examining the efficacy and safety of CDRI 08 in male children aged 6–14 years with high levels of inattention and hyperactivity. The primary outcome variable will be the level of hyperactivity and inattention measured by the Conners’ Parent Rating Scale (CPRS. Secondary outcome variables include cognition, mood, sleep, and EEG. Trial registration: Australia and New Zealand Clinical Trials Register (ANZCTR: ACTRN12612000827831.

Objectives were to use orchidometer for assessment of male puberty, to compare it with physical growth parameters and to compare orchidometry with Tanner’s Sexual Maturity Rating (SMR. Subjects were classified into adolescent staging by age, SMR & orchidometry. Results prove that orchidometry can substitute SMR staging in adolescent male, which is a time tested method. It is a rapid, non-invasive, easy & more objective method to assess male puberty in a busy office practice. Early identification of abnormal pubertal growth, counseling, appropriate follow-up & referral are possible using orchidometry

  13. Narcolepsy in adolescents.

    Sullivan, Shannon S

    2010-12-01

    Narcolepsy is a disorder of children and adolescence, but until recently it was often not identified until adulthood, with a reported time from onset to diagnosis of about a decade. This disorder affects approximately 0.05% of the population and starts in childhood and adolescence about half of the time. With narcolepsy, the boundaries between wake, sleep, and dreams are blurred. The cardinal features of narcolepsy-cataplexy are daytime somnolence, cataplexy (sometimes occurring long after onset of sleepiness), sleep paralysis, and hypnagogic hallucinations. Weight gain, disturbed nocturnal sleep, and social/school functional changes are common; reactive substance use to maintain wakefulness during the day may also be seen. Males and females are equally affected. It is classically associated with HLA DQB1*0602, the most specific genetic marker for narcolepsy across all ethnic groups. CSF hypocretin has recently been found to be depleted in this disorder, and late-breaking data support that the disease is caused by autoimmune destruction of hypocretin-producing neurons in the hypothalamus. There is no known cure for narcolepsy. Therapies include behavioral/ scheduling modification, medications to combat daytime sleepiness and cataplexy, and treatment of concomitant disorders leading to daytime sleepiness. The differential diagnosis for this disorder should include other disorders of excessive daytime sleepiness with a proclivity toward onset in adolescence, such as delayed sleep phase syndrome, obstructive sleep apnea, and insufficient sleep time; substance use; and less commonly neurologic disorders such as Klein Levin syndrome, Prader-Willi syndrome, and others. Immunomodulator therapy and hypocretin replacement are proposed therapies that hold promise for the future. PMID:21302860

    2014-03-01

    Full Text Available strongBackground: Recent studies have highlighted the co-occurrence of gender dysphoria (GD in adolescence and Autistic Spectrum Conditions (ASC. Systemising and empathising are two psychological dimensions linked to ASC. People with ASC score below average on the Empathy Quotient (EQ and average or above average on the Systemising Quotient (SQ. Based on the results of previous studies we predicted that if the young people with GD shared aspects of the ‘broader autism phenotype’, their EQ would be lower, and their SQ would be the same or higher, compared to controls of their natal gender. Methods: This preliminary study examined systemising and empathising in adolescents with GD using parent report questionnaires. 35 parents of adolescents with GD aged 12-18 attending the Gender Identity Development Service (London took part. Parents of 156 typically developing adolescents aged 12-18 were used as a control group. The parents were asked to complete the Adolescent EQ and SQ. Results: The mean EQ score of both the female-to-male, and male-to-female GD group was found to be significantly lower than typically developing females, but similar to that of control males. There was no significant difference on the SQ between the gender dysphoric groups and either female or male controls. Conclusion: This study shows that on average adolescents with GD, specifically those who are female-to-male, have lower empathy than controls. For this group of adolescents it may be helpful to offer psychological interventions that improve their communication skills and their ability to take on board other people’s views, to support their development. This may enable them to make better informed decisions regarding treatment and physical intervention options during adolescence and beyond.

    Detailed research examining concurrent longitudinal and secular changes in adolescent beverage intake is not currently available, particularly since the year 2000. This study's objective was to evaluate these trends in beverage intake in a large, diverse adolescent cohort. Project EAT (Eating Among Teens)-II is a 5-year longitudinal study (n=2,516) including two cohorts, which allows for the observation of longitudinal changes from early to mid-adolescence (junior high to high school) and from mid- to late adolescence (high school to post high school). Project EAT-II also examined secular trends in adolescent health behavior from 1999-2004 in mid-adolescence. Daily beverage servings were assessed using the Youth and Adolescent Food Frequency Questionnaire. Longitudinal findings indicate that intake of soda and sugar-sweetened beverages (including soda, sweetened iced teas, and fruit drinks) increased significantly among younger males, and alcohol increased across all groups (Pcoffee/tea (all males and younger females, Pcoffee/tea for males and females (P< or =0.05). Overall, these findings reflect recent secular and longitudinal shifts in adolescent beverage consumption during the critical transition period from early to mid-adolescence and mid- to late adolescence. Although additional research is needed to better understand nuances in adolescent consumption patterns, registered dietitians and other health care practitioners working with adolescents should address the importance of limiting sugar-sweetened beverages with low nutrient density.

    In spite of the wide range of injuries in adolescents during sports activities, there are only a few studies investigating the type and frequency of sport injuries in puberty. However, this information may help to prevent, diagnose and treat sports injuries among teens. 4468 injuries in adolescent patients were treated over a ten year period of time: 66,97% were boys and 32.88% girls. The most frequent sports injuries were football (31.13%) followed by handball (8.89%) and sports during school (8.77%). The lower extremity was involved in 68.71% of the cases. Knee problems were seen in 29.79% of the patients; 2.57% spine and 1.99% head injuries. Injuries consisted primarily of distortions (35.34%) and ligament tears (18.76%); 9,00% of all injuries were fractures. We found more skin wounds (6:1) and fractures (7:2) in male patients compared to females. The risk of ligament tears was highest during skiing. Three of four ski injuries led to knee problems. Spine injuries were observed most often during horse riding (1:6). Head injuries were seen in bicycle accidents (1:3). Head injuries were seen in male patients much more often then in female patients (21:1). Fractures were noted during football (1:9), skiing (1:9), inline (2:3), and during school sports (1:11). Many adolescents participate in various sports. Notwithstanding the methodological problems with epidemiological data, there is no doubt about the large number of athletes sustain musculoskeletal injuries, sometimes serious. In most instances, the accident does not happened during professional sports and training. Therefore, school teachers and low league trainer play an important role preventing further accidence based on knowledge of individual risk patterns of different sports.It is imperative to provide preventive medical check-ups, to monitor the sport-specific needs for each individual sports, to observe the training skills as well as physical fitness needed and to evaluation coaches education.

    Elisabetta Crocetti

    Full Text Available Adolescents' behavior is often a matter of concern, given their increased likelihood of enacting antisocial behaviors, which cause disruptions in the social order and are potentially harmful for the adolescents themselves and for the people around them. In this six-wave longitudinal study we sought to examine the interplay among maternal empathy, multiple indicators of mother-adolescent relationship quality (i.e., balanced relatedness, conflict, and support, and adolescent antisocial behaviors rated both by adolescents and their mothers. Participants for the current study were 497 Dutch adolescents (56.9% males followed from age 13 to 18, and their mothers. A series of cross-lagged panel models revealed reciprocal associations between maternal empathy and mother-adolescent relationship quality and between mother-adolescent relationship quality and adolescent antisocial behaviors. Interestingly, we also found some indirect effects of adolescent antisocial behaviors on maternal empathy mediated by mother-adolescent relationship quality. Overall, this study further highlights a process of reciprocal influences within mother-adolescent dyads.

    The risk of adolescent violent victimization in the United States varies considerably across racial and ethnic populations; it is unknown whether the sources of risk also vary by race and ethnicity. This study examined the correlates of violent victimization for White, Black, and Hispanic youth. Data collected from 11,070 adolescents (51 % female, mean age = 15.04 years) during the first two waves of the National Longitudinal Study of Adolescent to Adult Health were used to estimate group-specific multilevel logistic regression models. The results indicate that male, violent offending, peer deviance, gang membership, and low self-control were significantly associated with increased odds of violent victimization for all groups. Some activities-including getting drunk, sneaking out, and unstructured socializing with peers-were risk factors for Black adolescents only; skipping school was a risk factor only for Hispanic adolescents. Although there are many similarities across groups, the findings suggest that minority adolescents are particularly vulnerable to violent victimization when they engage in some activities and minor forms of delinquency.

    This study investigated the willingness of Israeli adolescents to seek help for emotional and health problems, and their preference for various helping agents. Nearly fifteen hundred students in grades 7-12 participated in a comprehensive survey of attitudes, health status, and concerns, and the data were analyzed. Gender and age were identified as factors associated with help-seeking attitudes. Females reported a higher level of distress and greater willingness to seek help than did males. Younger adolescents tended to state that they would turn to parents for help, whereas older adolescents increasingly preferred peers. In general, the adolescents preferred to seek help from family and peers for emotional and social problems, rather than turning to professionals. Adolescents in grades 9-10 reported the highest level of distress and were least willing to seek help for interpersonal problems and depressed mood. Overall, level of distress was not directly related to willingness to seek help. In subgroups of depressed and suicidal adolescents, an inverse relationship was found between willingness to seek help and levels of depression and suicidal ideation. Recommendations for health care services and counseling programs are discussed. PMID:11572304

    The present study (a) tests main and moderational effects of neighborhood and family risk, and adolescent impulsivity on the development of male and female antisocial behavior (ASB) and (b) examines the extent to which these effects work indirectly through parental knowledge. Adolescents (N = 4,597; 51% male) reported on informal social control in their neighborhoods, their family types, and impulsivity at age 12, and on parental monitoring and ASB at ages 13 and 15 years. Neighborhoods were further defined as risk and nonrisk in economic deprivation by census-level data. Main effects of neighborhood risk, single parenthood, and impulsivity on ASB were found for male and female adolescents. For female adolescents, impulsivity interacted with neighborhood economic deprivation and with family type in the prediction of parental knowledge. Impulsivity and contextual risk factors in part increased adolescent ASB through decreasing parental knowledge. Theoretical and policy implications are discussed. PMID:20677842

    While much is known about adolescent delinquency, considerably less attention has been given to adolescent delinquency abstention. Understanding how or why some adolescents manage to abstain from delinquency during adolescence is informative for understanding and preventing adolescent (minor) delinquency. Using data from the Cambridge Study in Delinquent Development (N = 411 males) to compare abstainers, self-report delinquents and convicted delinquents we found five childhood factors (ages 8-10) that predicted adolescent abstention (ages 10-18). First, we find that adolescent abstainers possess characteristics opposite to those of convicted delinquents (namely, abstainers are high on honesty, conformity and family income). However, we also found that abstainers also share some childhood characteristics with convicted delinquents (namely, low popularity and low school achievement). A latent class analysis indicated that the mixed factors predicting abstention can be accounted for by two groups of abstainers: an adaptive group characterized by high honesty, and a maladaptive group characterized by low popularity and low school achievement. Further, validation of these two types of abstainers using data collected at age 48 suggested that adaptive abstainers outperform all other adolescents in general life success, whereas maladaptive abstainers only fare better than delinquent adolescents in terms of lower substance use and delinquency later in life.

    It has been demonstrated that disruption of social bonds and perceived isolation (loneliness) are associated with an increased risk of cardiovascular morbidity and mortality. Adolescence is proposed as a period of vulnerability to stress. Nevertheless, the impact of chronic social stress during this ontogenic period in cardiovascular function is poorly understood. Therefore, the purpose of this study was to compare the impact in cardiovascular function of social isolation for 3 weeks in adolescent and adult male rats. Also, the long-term effects of social isolation during adolescence were investigated longitudinally. Social isolation reduced body weight in adolescent, but not in adult animals. Disruption of social bonds during adolescence increased arterial pressure without affecting heart rate and pulse pressure (PP). Nevertheless, social isolation in adulthood reduced systolic arterial pressure and increased diastolic arterial pressure, which in turn decreased PP without affecting mean arterial pressure. Cardiovascular changes in adolescents, but not adults, were followed by facilitation of both baroreflex sensitivity and vascular reactivity to the vasodilator agent acetylcholine. Vascular responsiveness to either the vasodilator agent sodium nitroprusside or the vasoconstrictor agent phenylephrine was not affected by social isolation. Except for the changes in body weight and baroreflex sensitivity, all alterations evoked by social isolation during adolescence were reversed in adulthood after moving animals from isolated to collective housing. These findings suggest a vulnerability of adolescents to the effects of chronic social isolation in cardiovascular function. However, results indicate minimal cardiovascular consequences in adulthood of disruption of social bonds during adolescence. PMID:25914339

  18. Routine Activities Preceding Adolescent Sexual Abuse of Younger Children.

    Leclerc, Benoit; Felson, Marcus

    2016-03-01

    Adolescent abuse of younger children has long been recognized, but empirical research on the circumstances of this phenomenon is rare. This article examines how adolescent offenders find and gain access to victims, work out time alone with them, and set up or exploit settings for sexual contact. Prior researchers learned that adult sex offenders use certain routine activities to perform these tasks. The current research inquires whether adolescent offenders are similar. We administered Kaufman's Modus Operandi Questionnaire to a sample of 116 Canadian adolescent males undergoing treatment for a sexual offense against a child. Adolescent offenders follow routines similar to adults but are better able to use games and activities as a prelude to sexual abuse. We discuss how routine legal activities set the stage for activities and should be considered when devising situational prevention strategies. PMID:25060598

    Adolescence is a critical period for neurodevelopment. Evidence from animal studies suggests that isolated rearing can exert negative effects on behavioral and brain development. The present study aimed to investigate the effects of adolescent social isolation on latent inhibition and brain-derived neurotrophic factor levels in the forebrain of adult rats. Male Wistar rats were randomly divided into adolescent isolation (isolated housing, 38–51 days of age) and social groups. Latent inhibition was tested at adulthood. Brain-derived neurotrophic factor levels were measured in the medial prefrontal cortex and nucleus accumbens by an enzyme-linked immunosorbent assay. Adolescent social isolation impaired latent inhibition and increased brain-derived neurotrophic factor levels in the medial prefrontal cortex of young adult rats. These data suggest that adolescent social isolation has a profound effect on cognitive function and neurotrophin levels in adult rats and may be used as an animal model of neurodevelopmental disorders.
